Tail light bulb doesn’t work? (Question)

First, check for corrosion and power at the tail light bulb socket. The most common cause of tail light problems is corrosion inside the tail light bulb socket. With the bulb out, look for green corrosion. If the bulb still doesn’t work, check for power in the bulb socket.

  • The common causes the tail lights do not work are; Blow fuse – The first thing the mechanics check is the fuse corresponding to the rear lights. When the fuse is blown it does not allow the circuit to complete.

What would cause tail lights not to work?

The most common reason why your tail lights are not working but brake lights are is due to a bad or wrong type of light bulb installed. It can also be caused by a blown fuse, bad wirings, or corroded sockets or plugs. A faulty control light switch could also be to blame.

Is there a fuse for each tail light?

On newer cars, the tail lamps can be fused separately and/or each bulb or shared circuit can be fused. A fuse can be blown due to other problems, so you’ll need to check more than just the fuse, but it’s the right place to start.

How do I know if my tail light socket is bad?

The socket may have gone bad Push the point of the tester through the wire insulation behind the socket to make contact with the wire. The tester should light for two of the three wires (the ground wire won’t light). If it lights for two wires, the wiring is good. Simply replace the socket.

What fuse controls the tail lights?

The tail light fuse may be located in either the fuse panel in the front passenger side of your vehicle or in the main fuse box under the hood. Once you’ve opened either the panel or the main fuse box, locate the tail light fuse. If you’re unsure which one it is, use the owner’s manual for guidance.

How do you check if your tail lights are working?

To test your brake lights and tail lights, get in your vehicle and turn on the ignition switch. You do not have to actually crank your engine. First, check your tail lights by turning on your headlights. If working properly, they will come on simultaneously and glow red.

How much does it cost to replace tail lights?

The average price for a whole light assembly – just one, mind – will cost you anywhere between $200, to $2,000 on the high-end. Luxury or exotic cars may even have a higher price tag than that. Older or economy cars are naturally cheaper to fix, as they generally use simple and conventional lights.

Why do I have tail lights but no brake lights?

Why is that? The most common reason your brake lights are not working but tail lights do is a bad light bulb. It can also be caused by a blown fuse, bad brake light switch, or issues with the wirings. Your vehicle’s taillights are working fine, but the brake lights don’t come on when you press the brakes.

Where is the fuse for the rear tail lights?

Like all fuses, the brake light system fuse can be found in the power distribution center, which is under the dashboard or tucked away underneath the hood.

Are brake light and tail light the same bulb?

On many vehicles, the tail lights and brake lights share the same bulb. One filament inside the bulb is for the tail light and the other filament is for the brake light. There are also some vehicles that have a separate bulb for each circuit.

Can you drive with no tail light?

While some police officers issue citations for broken taillights – which they can do, as it is technically illegal to drive with a broken taillight – most will probably just give you a warning and tell you to get it fixed as soon as you can.

6 Reasons for Tail Lights Not Working but Brake Lights Are (EASY Fix)

The most recent update was made on January 5, 2022. Tail lights are an extremely vital safety component on any automobile. They are required when driving at night or during twilight hours, as well as in inclement weather such as rain or snow. Are you looking for a reliable online repair manual? The top five choices may be found by clicking here. You use your tail lights to brighten the area behind your vehicle during night time. Most of the time, they are activated when you flick on the switch that also activates your headlights.

Tail lights, like every other component of a vehicle, are susceptible to failure, posing a serious safety hazard.

What happens, though, when your brake lights function but your tail lights do not?

6 Common Causes for Tail Lights Not Working But Brake Lights Are

When dealing with an electrical component that isn’t working properly, especially when it comes to faulty tail lights, the first thing to check is the fuse. In its most basic form, a fuse consists of a metal band enclosed in a plastic container that is designed to rupture when the current flowing through it becomes excessive. As a result, other sections of the electrical system are kept from being destroyed as well. Typically, there are two spots in an automobile where fuses may be found.

  • One of these is a fuse panel located inside the vehicle’s cabin. This is usually located on the front passenger side of the vehicle, behind a plastic plate beneath the dashboard. It can be located on the side of the dash if the passenger side door is fully opened
  • The second most typical location to discover fuses is in the main fuse box under the hood of some vehicles. Essentially, it’s a large black box with several wires running through it. Once the top cover has been removed, you will be able to see the fuses that are contained within it.

Each fuse is in charge of a distinct electrical component, and the functions of each fuse should be indicated on the cover that you removed in order to have access to the fuses. If not, they can be recognized by consulting the owner’s handbook or by searching online for a schematic that corresponds to the year, make, and model. Once the fuse that controls your tail lights has been located, it may be examined with a fuse tester, which will illuminate if the fuse is in good working order. If the fuse does not light up, it should be replaced with one that has the same size and amperage as the original.

2 – Bad Tail Light Bulbs

If the fuses beneath the hood and within the cab are found to be in good working order, the next suspect to investigate is the tail light bulbs themselves. It’s usually necessary to remove the tail light cover, however some vehicles have an access panel that allows you to reach in and twist the bulb out of the lens without removing the cover. The most accurate approach to determine if a bulb is faulty is to remove it from the socket it is currently connected into and carefully check the filament.

It is necessary to replace a broken filament with a new bulb if the filament is no longer illuminated. What if you’ve already replaced the light bulb with a new one and the problem persists? Please continue reading. Related: 5 Reasons Why Your Turn Signal Is Blinking Too Quickly

3 – Socket Failure

It is possible for the socket into which the bulb is inserted to malfunction. Typically, corrosion is the source of this, which is brought on by moisture entering the plug socket. However, it is possible that it will fail as a result of a faulty connection of the wires in the rear. If the bulb and fuse both appear to be in excellent working order, you should inspect the condition of the socket while the bulb is removed. Examine the pins for any discolouration, such as white, blue, or brown, as well as bent or broken pins.

No energy reaching the pins indicates that there is a problem further up the electrical cable.

4 – Worn Out Wiring

The most likely cause of a lack of electrical power flowing into the socket, after all fuses have been examined and found to be in excellent working order, is a damaged or broken wire somewhere along the line. This is the stage at which you’ll need to get a wiring schematic and visually examine the wires running through the tail light circuit for broken wires or cracked insulation, among other things. Check the body grounds that are coming off of this circuit as well. Additionally, a filthy, loose, or damaged ground wire will result in an interruption in the flow of power to the sockets.

5 – Control Switch Failure

Another reason for the failure of the tail lights to illuminate is a problem with the switch that controls them. The headlight switch on the dashboard might also fail, and it should be examined if everything else has been tested and found to be in working order. Under normal circumstances, this switch activates the headlights, taillights, and parking lights. The possibility that this switch has failed exists if all other components of the tail light circuit are in proper operating condition. This may be removed from the dashboard and tested with a multimeter to determine whether or not it has failed.

6 – Dirty or Bad Ambient Light Sensor

A sensor for ambient light is also found on the dashboard of many contemporary automobiles. This enables the vehicle’s computer to automatically turn on and off the headlights and tail lights based on how bright or dim the outside light is at any given time. Some people also choose to switch off the daytime running lights on their modern automobiles. If your parking lights and headlights do not illuminate, but your brake lights do, this is most likely the source of the problem. If this sensor becomes faulty or becomes too dusty, it will be unable to determine whether it is day or night outside and will thus fail to switch on the lights.

Conclusion

Overall, tracing out an electrical breakdown may be a difficult and irritating task to say the least. Fortunately, tail light bulbs are often operated on their own separate circuit, making it quite simple to identify and resolve problems. All of these failures will result in the inability to operate the tail lights, but they will not prevent the brake lights from turning on when the pedal is depressed since the brake lights operate on a separate line of circuitry.

When a driver notices that their tail lights are not working, they should rectify the issue as soon as possible to ensure their own safety and the protection of others.

Tail Lights Not Working But Brake Lights Are? (How To Fix)

The longer you have had your car, the more probable it is that you may experience electrical difficulties at some point during that time. While most of the time, such issues are as simple as burned bulbs and blown fuses, there are times when they may get a little more involved. Don’t be anxious; even if you’re stressed out and concerned about the cost of repairs, the answer is generally less complicated than you anticipate it would be. Here are the most typical reasons why your taillights are not working, yet your brake lights are still working, as shown below.

Additionally, a blown fuse, faulty wiring, or corrosion in the sockets or plugs might create this problem.

While not all of the probable reasons are included below, they are the most often seen.

6 Taillights Don’t Work But Brake Lights Do Causes

Brake lights are commonly equipped with a twin filament bulb, and it is possible for just one of the filaments to become damaged or broken. When this occurs, one side of the bulb, such as the brake light, will operate properly, but the other side, such as the taillight, will not. Furthermore, several automakers utilize different bulbs for the taillights and the brake lights on their vehicles. The taillight bulb will need to be replaced if it becomes damaged or burnt out. After everything is said and done, it’s possible that you’re utilizing the wrong bulbs if you’ve only recently changed them.

That is not correct.

In the event that you’ve already disposed of your old bulbs, consult your owner’s handbook or Google to see if you can locate the suitable bulb for your car!

2. Blown Fuses

The most likely cause of your vehicle’s taillight failure is a blown taillight fuse, which may be identified by the presence of a few burned-out bulbs. Finding your vehicle’s fuse box and checking the fuse with a test light or a multimeter are the only things you need to do to check. It is sufficient to just remove the taillight fuse and examine it if you do not have either. If you’re not sure whether or not the fuse has burned out, try swapping it out with another fuse of the same amperage. If the problem is moving, then the fuse is the source of the problem.

When purchasing a replacement fuse, make sure to choose the appropriate amp fuse. It might be tempting to increase the amperage in order to guarantee that the fuse does not blow again, but doing so can cause worse difficulties if the fuse does not safeguard the system as it should!

3. Faulty Control Switch

Although it is commonly overlooked by do-it-yourself technicians, it is one of the most common causes for your taillights to quit operating. The control switch in the cab of your car informs your taillights when to turn on and off, and if the switch isn’t operating properly, you’ll never be able to turn your taillights on! When this element fails, you will almost always lose the ability to use the front parking lights as well.

4. Wiring Issues/Bad Grounds

Troubleshooting wiring problems are the misery of many a mechanic’s existence. Despite the fact that they might be difficult to debug and determine the specific problem, they continue to appear on sometimes. A typical problem with older automobiles is that the wiring is faulty, the lines are crossed, and the vehicle is corroded beyond repair.

5. Corroded or Damaged Sockets or Plugs

Everything inside your car becomes exposed to the elements if the taillights aren’t securely sealed once they have been installed. While this can result in issues throughout the system, the socket itself is the most vulnerable point. Because they are exposed to the weather, these sockets are susceptible to rusting and corrosion, which can result in a variety of electrical difficulties. When replacing a bulb, it’s important to check the socket to make sure it’s in excellent working order as well as the bulb.

However, if the damage is severe enough, you’ll have to have the socket replaced entirely.

6. Bad Ambient Daylight Sensor

When it is dark outside, modern automobiles are equipped with automated parking lights. This implies that they will turn off if there is enough light outside to see through them. Although this varies depending on where you live, have you checked to make sure that it is not too bright outside for your tail light to turn on? In other cases, however, it might be caused by a malfunctioning ambient light sensor, which informs the vehicle when it is appropriate to turn on the taillights. A popular location for this sensor is in the front windshield, and it is not very usual for it to fail due to wear.

Tail Light Troubleshooting Guide

The KISS principle must be followed while solving problems. Of course, this is not a literal translation, but you must keep things simple, dumb! It is, in its most basic form, the principle of Occam’s Razor, which states that the simplest answer is generally the issue. Ensure that the lights haven’t burned out and that you are receiving electricity before you begin digging into wire harnesses and verifying grounding points. No power is generally indicative of a blown fuse, although it might also indicate a malfunctioning switch.

  1. They are also the most straightforward to debug and repair, which is even better for you!
  2. To begin, check for power at the socket, but only with a known good ground as a starting point.
  3. If rust or anything else is covering the terminal, you’ll need to clear it off first before proceeding with installation.
  4. However, if you’re getting power and there’s no corrosion, the problem is most likely a grounding issue that has to be addressed.
  5. It is possible that you have a wiring problem between the socket and the fuse if the fuse is receiving electricity but the socket is not.

Once again, if you have power at the switch but not at the fuse, the wiring issue is somewhere in the middle of the system. However, if you aren’t getting power to the switch, the problem is likely somewhere between the switch and the battery itself.

Summary

When it comes to electrical gremlins, nothing is more aggravating. The good news is that with a little automotive know-how and a fundamental grasp of electrical principles, there’s no reason you can’t hunt out the source of your malfunctioning lights! It may seem intimidating at first, but the majority of electrical problems are inexpensive to repair and will not recur if the task is done correctly the first time. Even better for rookie technicians, they are difficulties that can usually be promptly troubleshooted and resolved by the individual.

Why Do My Brake Lights Work but My Tail Lights Don’t?

Car problems are something that everyone has to deal with at some point in their lives. These issues might range from minor inconveniences to major headaches that can cost you a small fortune in repairs. As a result, it’s important to keep an eye out for problems with your vehicle before they get too serious. You should pay close attention to the headlights and tail lights of your vehicle. Many of you may be perplexed as to why my brake lights are operational yet my tail lights are not. If you happen to be one of them, then this is precisely what you need to be reading at this time.

Why Do My Brake Lights Work but My Tail Lights Don’t

Why do my brake lights work but my tail lights do not? In this section, we’ll go over the most likely explanations for this.

Faulty Tail Light Bulb

One of the most common reasons why you could notice your brake lights functioning while your tail lights are not is that the bulbs put in the tail lights were broken when you purchased the vehicle. You need conduct some tests to determine whether or not the bulbs are the primary cause of the problem, and in order to do so, you will need to remove the tail light cover. It is not a tough task that you have before you. It is necessary to ensure that the filament in the bulb is operational. If you observe illumination, it means that the system is operational and that something else is causing the problem.

As a result, replace the bulbs.

The majority of them will assist you in achieving your desired result.

Problematic Fuse

More than just the broken bulbs, you will notice that there is something wrong with the fuse, which is responsible for ensuring that the entire electric system of the automobile operates smoothly and without causing any harm. Its primary function is to trip when the current flow becomes excessive. The electric system is safeguarded by this rupture. Now, if you want to check the fuse, there are two locations you may look in the automobile to find it. The first is the fuse box. The first one may be found on the panel located in the cabin of the vehicle.

  1. The second location is directly beneath the hood of the vehicle.
  2. All that is required is that you determine which fuse is blown.
  3. When the lid is removed, it is possible to access the fuse.
  4. This is something that you should be able to discover in the owner’s handbook or on the internet if you search for it.

If it is not up and running, check with a fuse tester to make sure it is. Whether or not it works may be determined by checking whether or not the tester is illuminated. If this is the case, everything is OK. If, on the other hand, it does not illuminate, you will have to get a new one.

Bad Bulb Socket

If you have already tested the fuse and the bulbs, and you have determined that they are both in perfect working order, the next item you should check is the socket. Sometimes a problem with the socket can result in the tail lights not working properly. Moist conditions have the potential to cause harm to the sockets. Building up of any form of moisture can cause problems with the wiring, which can eventually result in failure of the circuitry. It is also possible that the sockets will not function correctly due to a faulty connection of the wiring.

You should either update it or get it checked out if this is the case for you.

So keep an eye out for any of these evident issues so that you can address them as soon as possible.

Well Worn Wiring

The electrical system is responsible for ensuring that everything runs smoothly. And if there’s a stray wire out of position, there’s a good probability. You won’t be able to proceed with this unless you have a suitable wiring diagram for the automobile. And you’ll have to track down the ones that are linked to the tail lights in order to figure out what’s going on with them. Googling around for a problem with the tail light is just too time-consuming and needless in this situation. As well as paying attention to a worn-out wire in the automobile, you should also pay attention to the ground circuit, which can occasionally cause an issue with the tail lights.

Faulty Light Sensor

Automobiles are becoming more equipped with automated functions as time goes on. This makes driving a whole lot less difficult for us. It has a light sensor, which is one of the novel features. In many cases, the computerized system of the automobile can determine when to turn on which light and when not to. If there is a problem with the sensor, it is possible that this is the cause of your tail lights not working. Even if the sensor may be programmed to turn off the lights during the day, it may be unable to distinguish between day and night due to malfunctioning.

It is possible that the sensor will become faulty, in which case you will need to have it repaired or replaced with a jeep light bar.

In that situation, a thorough cleaning will be sufficient.

Failure in the Control Switch

Control Switch failure is a common occurrence. Your tail light could not be working even when your brake lights are operating due of a faulty control switch, which is the absolute last possible explanation. When you wish to turn on the headlights or the tail lights, you must touch a button on the steering wheel. It sends the signal, and the lights begin to operate as a result of that. If the switches were not functioning properly, there would be no signal produced. You may not be able to find this out on your own, but if you have explored all other possibilities, it is possible that the control switch is to blame for all of the problems you are experiencing.

To ensure that everything operates well, you can always show it to someone with more expertise or take it to a professional who will ensure that everything runs properly.

Conclusion

The solution to your query about why my brake lights function but my tail lights do not should be revealed at the conclusion of this section. Just have a look around and you should be able to find the solution to your inquiry!

Brake or tail light is not working: what are the repair options and cost?

14th of February, 2021 (updated). If you look at your vehicle, you will find that one of your brake or taillights is not working. What are your repair choices and expenses if your vehicle is no longer covered under warranty? LED taillights are standard on many current vehicles, and they are frequently changed as a unit. If it’s only a blown bulb, it’s a relatively inexpensive problem to fix. The right-side brake light is not working. A local dealer or vehicle repair business may be able to assist you if you do not wish to change the bulb yourself.

  • In some vehicles, changing a bulb is straightforward; however, in others, the taillight assembly may need to be removed in order to do so.
  • The varieties of bulbs available for your vehicle are listed in the owner’s handbook, which may also provide instructions on how to change a bulb.
  • Often, the kind of bulb is printed directly on the bulb itself.
  • The owner’s handbook for this Honda Accord, for example, states that: Turn the socket one-quarter turn counterclockwise to remove it.
  • Take the bulb out of the socket by pulling it straight out.
  • Reassemble the light assembly by reinstalling the socket.
  • When replacing a light bulb, you may also mark the location of the previous bulb with a marker or take a photo of it before removing it to make the process easier.

How long do automobile bulbs last before they need to be replaced?

Many factors, like where the bulb is positioned and how good the bulb is, influence how long it lasts.

Inspecting the bulb is a good idea to ensure it is in excellent working order.

If the socket appears to be in good condition, the fuse, the wiring to the bulb, and the connection must all be examined.

The majority of the time, it’s easy to tell when a light bulb has burned out.

It is also possible to examine it by measuring the resistance of the bulb using a multimeter as an alternative method.

If the multimeter displays OL, which indicates that the resistance is out of range (i.e.

It’s also feasible to test the bulb using a 12V power supply or a 9V battery if you have one on hand.

When one filament dies, it is common for the other to continue to function.

Is it possible that a defective bulb socket is causing the light to not work?

Does it appear to be charred or melted?

Often, the bulb does not operate because the socket is broken or has a faulty connection; for an example, see the photograph.

If your local parts store does not have it in stock, you can have it special ordered from a dealer.

In certain vehicles, the socket is included as part of the taillight wiring harness, which can range in price from $15 to $35.

Despite the fact that it is unusual for two or three bulbs to fail at the same time, it is necessary to examine the bulbs first.

If the bulbs are in excellent working order, it is likely that the electrical circuit for the afflicted lights is malfunctioning.

If the electric circuit is not functioning properly, the first step is to examine the fuse.

A fuse can be used in more than one circuit at the same time.

Electronic control modules are used to regulate the lighting in modern automobiles.

Fuse for the affected lights has been blown, so what should you do now?

For example, one of the bulbs might be shorted or put in the incorrect orientation.

Wires that have been damaged within the trunk lid harness may also short between each other, resulting in the fuse blowing.

However, a skilled technician should be able to identify the source of the problem and fix it. When dealing with an electrical problem like this, most dealerships and car repair companies charge a fixed cost ($50-$130) for the first tests.

Tail Lights Not Working But Brake Lights Are: Fixed (Answer)

Taillights are extremely important in maintaining a safe driving distance, especially at night. You may, on the other hand, discover that your tail lights are not functioning, although your brake lights are. Despite the fact that your brake lights are completely operational, other cars travelling behind you may not be aware of your presence. It is possible that an accident will occur as a result of malfunctioning tail lights. Tail lights and brake lights that are not working might be caused by a variety of factors.

Reasons Why This Can Happen

In your car’s taillights, light bulbs are used, which function in a similar way to the light bulbs in your home. As a result, much like your household bulbs, your tail lights are susceptible to being burned. Furthermore, the brake lights and tail lights on your automobile require various types of light bulbs. As a result, the taillight bulb may become damaged while the brake lights are unaffected. The outcome is that your brake lights will operate, but your tail lights will not work as a result of this.

2. Dislocated or Damaged Wiring

Tail lights can be rendered inoperable by damaged or interrupted wiring, whereas brake lights are unaffected. Because each bulb has its own power supply, the wiring for the two lighting fixtures is distinct. A recent collision that occurred in the rear of your vehicle might enhance the probability of this problem occurring. As a result, if the cables connecting the breaking lights are not destroyed, the lights may be operational. This problem happens when there is a severe or complete failure of the power wires.

3. Blown-out Fuse

Similarly, a blown fuse might be another reason for the inability of the tail lights and brake lights to function properly. Each electronic component in your vehicle is connected to its wick. As a result, when a certain fuse breaks, the light associated with it stops operating. This functionality explains why taillights may fail to operate while brake lights continue to function properly. When a fuse blows, it causes the circuit to be turned off. Check your fuse to see if the problem is with your tail lights or with your fuse box itself.

4. Electrical Problems

Another issue that might cause your tail lights to stop operating is an electrical malfunction. In this instance, though, you will need to take your vehicle to a technician. A blown fuse and poor wiring cause a domino effect that results in electrical difficulties, which are common in the home.

How to Check Each Component

You should check a variety of factors in order to determine whether your tail lights are malfunctioning. One of the things to look for is a burned out bulb, which is an easy task to complete. Either the trunk or the lenses can be removed in order to get access to the light. After that, you may unscrew the bulbs and look for any that have been darkened. Additionally, the automobile dashboard contains a signal indication that indicates when a bulb is not functioning properly. You may also use this signal indicator to determine whether or not your bulbs are malfunctioning.

Another method is to check to see if the filament of your light is still intact. The thread on the working bulbs is still intact. If it turns out that your bulbs are the source of the problem, all you have to do is change them. Obtaining car bulbs may be accomplished at a local automotive store.

2. Damaged or dislocated wiring

It is simple to determine the condition of your taillight wiring. To obtain access to the wiring, you must first open the trunk and remove the cover. If the wires are not properly secured, this might be the source of the problem with the tail lights. To correct the situation in this scenario, you just need to reconnect the cable connections. For severed wires, on the other hand, you will need to take them to a technician for appropriate repair.

3. Blown-out fuse

It is possible that a blown fuse can result in your tail lights not working. The automobile fuse appears to be identical to any other fuse on the market. It is necessary to first find the fuse box in order to inspect this component. However, while you are inspecting the fuse box, make sure to turn off the car’s ignition. Making sure that the car’s ignition is turned off may spare you from an electric shock. The use of a flashlight might assist you in identifying the fuse for the tail light. After you’ve determined which fuse to use, you’ll need to remove it and check it.

A broken wire, on the other hand, shows that the wick is defective.

Fuses have a wide range of voltages, therefore you must make sure you are using the correct fuse.

4. Electrical problems

Last but not least, you must investigate the electrical problem. When fuses and wires fail, the most common cause of mechanical failure is the result of the repercussions of the failure. Mechanics, on the other hand, are in a better position to identify and correct such problems.

5. check Wiring

When your tail lights stop working but your brake lights are still working, you should check your wiring. It’s possible that the rats chewed away at the wiring in your car’s interior. As a result, you must double-check that all of the connections are tightly secured together before proceeding. In addition, it is necessary to examine the wiring schematic for accuracy. It will assist you in understanding how your automobile’s lighting system operates and will instruct you on how to make modest adjustments.

  1. Corrosion might also be a contributing factor to bad wiring.
  2. As a result, dampness can cause rust to form, which can cause the entire electric circuit to malfunction.
  3. Checking the wiring also gives you the opportunity to detect a problem with your automobile at an early stage.
  4. You will also have a greater understanding of your automobile.

6. Check Turn Signal Switch

In certain automobiles, the switch for the tail lights receives its electricity from a single electrical circuit. This includes the turn signal light as well if the situation calls for it. This function, however, is not available in every automobile. As a result, a wiring diagram should be used to determine whether or not your vehicle runs in this manner. This illustration will assist you in determining whether or not the wires are traveling through the switch signal turn or not. Identifying the cable that links the turn signal switch to the tail lights, on the other hand, is essential.

Following that, your tail lights should normally function properly, resulting in a safer driving experience for you.

As a result, the likelihood of an accident occurring is reduced.

In order to ensure that your car is in excellent working order, it is necessary to inspect it on a regular basis. Additionally, evaluating your automobile allows you to identify any potential problems with it as soon as possible. It also assists you in keeping it in good condition.

Conclusion

It is also necessary to do regular inspections on your vehicle if you own one. This check will assist you in ensuring that every component is in proper working order. As a consequence, you will be more cautious when driving. When driving a car, lights are vital since they assist you to be more visible on the road. When you are driving a car without taillights, you run the risk of being struck from behind by another vehicle. Other drivers may not be able to see you, especially if you are driving in a dark automobile.

  1. In addition, you must understand how to recognize a burned-out light bulb and how to replace it.
  2. This information is critical in assisting you with repairing the light on your own.
  3. Furthermore, you must be familiar with the process of checking and identifying blown-out fuses.
  4. You should be able to provide the relevant knowledge on how to identify and correct wiring issues.
  5. It allows you to become more alert and to be able to tackle some problems without having to call a mechanic for assistance.

If your car’s tail lights are not illuminated or are faulty, you may be issued a citation by a traffic officer, so don’t spend any time. Continue reading to find out how to fix your car’s tail lights.

  1. 1 Make sure the fuse is in good working order. Typically, a blown fuse results in the failure of both lights. When driving a more recent vehicle, the tail lights can be fused individually, and/or each bulb or shared circuit can be fused. Fuse failure can be caused by other issues, so you will need to examine more than just the fuse, but it is a good place to begin your investigation. Look in your owner’s handbook to find out where the fuse box is situated in your vehicle’s engine compartment. The fuse box is often found under the dash of older automobiles. It may be found beneath the hood or on the dashboard of most modern automobiles. The fuse box will be depicted in the handbook with labels indicating which fuse is connected to which circuit. Make sure the ignition is turned off before removing the top from the fuse box and locating the taillight fuse within. Examine the fuse with a flashlight to see whether it has blown and take the appropriate action. Because of the way the fuses are organized in most modern automobiles, it is necessary to remove the fuse in order to inspect it.
  • If the chunk of metal within the taillight fuse is still in tact, the fuse is still in good working condition. It is likely that the fuse has blown and that it will need to be replaced if the metal component seems damaged or cracked. To remove the fuse, use your fingers or a tweezer to pry it out. The fuse extractor is usually found in the fuse box or in the tool kit of most new autos. It’s a little white plastic instrument that looks like a pair of pliers and is used to open packages. If you can’t find a match at an auto store, you can purchase a replacement and install it in the right position to replace the blown fuse.
  • 2 Take a look at the wiring for the tail lamps. These are the wires that connect the tail lights to the rest of the vehicle, and they are positioned inside the trunk lid. Open the trunk and have a peek at the contents. It is possible to observe where the wires need be connected in order for the electrical system to function properly. If a wire has fallen loose, it should be reconnected.
  • Typically, in new automobiles, the wire harness is hidden behind panels in the trunk and is not accessible without first removing the panels.

  • s3 Check the bulbs in the taillights. If the fuse and wiring appear to be in proper working order, the bulbs themselves may be the source of the problem. Using a screwdriver, detach the taillight lenses from the outside of the vehicle to inspect them. If your lenses do not have screws, you will need to open the trunk in order to have access to the lights on the interior. Remove the bulbs in concern and examine them in the same way you would any other household bulb: by inspecting the filament wire within them to discover if it is still in good condition. It is possible to test the bulb by tapping it on your hand to see whether the filament moves or vibrates
  • In addition to stop lamp/turn indicator bulb(s), reverse lamp bulb(s), tail lamp bulbs, side marker bulb(s), and on certain models, a self-standing turn indication bulb, most tail lamps are equipped with. When the brake and turn signal indicators are both illuminated by the same bulb, the turn signal indication will flash more quickly than normal when the bulb is burned out. Additionally, if the vehicle’s rear amber turn indicator has a burned-out turn signal bulb, the above rule will apply. If the bulb is completely burnt out, you’ll need to replace it immediately. Go to your neighborhood auto store and purchase the suitable model for your vehicle. If the bulb is in good working order, your automobile may be suffering from a more serious electrical problem. After checking that the fuse, taillight wiring, and bulb are all in excellent working order, it’s time to take your automobile to the repair. Inspect the socket for burned contacts and the tail lamp for burned contacts or melted socket boards when you remove a bulb to replace it.
  1. 4Inspect the lenses of the taillights. Regardless of whether or not you were successful in resolving the issue with your tail lights not working properly by inspecting the fuse, wiring, and light bulb, it is critical to check the lenses to ensure they are not cracked or damaged. Water getting into the lens might cause a bulb to burn out. Continue reading to find out how to fix a damaged or cracked lens in your car. Advertisement
  1. 1 Remove the taillight lens
  2. 2 Use lens repair tape to patch up any breaks in the lens. The use of tape is intended to be a temporary solution. You may either purchase tape or get a lens repair kit that includes resin that you can easily apply over the break to make it watertight once again.
  • It is necessary to thoroughly clean and dry the area where the tape will be put. After rubbing alcohol has been used to clean the area, wash it down with a lint-free cloth dampened with rubbing alcohol and allow it to dry before applying the tape. It is not recommended to clean the area with glass cleaner since the ammonia in the glass cleaner will cause the tape to not adhere as well as it should to the surface. Using rubbing alcohol as a last wipe, you may eliminate the majority of the contaminants and leave a clean surface. Measure the size of the fracture and cut the tape so that it is slightly bigger in diameter than the damage to the lens
  • Remove the tape’s backing from the surface
  • Make sure to smooth down any air bubbles when you’re applying the tape to avoid their distorting the lens.
  • With lens repair glue, you may fill in any holes or cracked regions. Filling a gouge or damaged place with plastic resin can be done if there is a large enough hole. Purchase a lens repair kit that includes materials for filling in the holes in the lens.
  • Fill up any gaps around the taillight with the plastic tape that came with it in order to prevent the plastic resin from leaking out. Prepare the resin mixture by mixing it with a catalyst and coloring agent according to the instructions that came with the kit. If you want to prevent getting resin on your skin at this stage of the procedure, put on a pair of disposable gloves. Fill the syringe with the resin that has been given. Squeeze the resin into the hole, making sure that it covers the whole area that has to be filled. Allow for a minimum of 2 hours of curing time. Remove the masking tape and sand the surface to make it more even.

What happens, though, if your taillights are operational but your brake lights are not?

Malfunctioning light bulbs

Light bulbs that have blown out are one of the most prevalent causes of brake lights that aren’t working. This is especially true for people who drive older automobiles. If you depress the brakes and the brake lights do not illuminate, immediately check for a defective light bulb in the brake light assembly. This examination and/or repair does not necessarily necessitate the use of a professional. All that is required is that you open your car trunk and remove the rear cover of the taillights.

If the bulb has become completely black or if you can see a damaged filament inside, it may be necessary to replace it.

Fuse box and light switch

A fuse box is where the cables that give energy to all of the electronic gadgets in your automobile are routed through. If you have a contemporary vehicle, you’ll need to hunt for two fuse boxes on the dashboard. Your car’s owner’s handbook will help you locate the brake light fuse.

It is possible that a blown fuse is responsible for brake light issues. If it has blown, it should be replaced with a new one. Check the amperage of the new unit to make sure it is the same as the old one and that it is the same voltage. If this is not done, the problem may continue to occur.

Electrical ground

Checking the electrical ground is one of the things you should do if the taillights and brake lights are not working is something else you should do. Especially in cases when the brake light switch is not functioning, this might be a potential problem. Poor electrical grounding, which might be caused by corroded or broken cables, should be looked for. It would be obvious that the ground connection required repair if the brake light illuminated while both the light switch and the brake pedal were connected to a good ground when the brake pedal was depressed.

Wiring

Providing the light bulb, fuse box, and electric ground are all in proper working order, there is one more item you may check to determine why the brake lights are not working – the brake light wiring. Examine the wiring that runs from the fuse panel to the brake light switch, as well as the wire that runs from the switch to the bulb sockets. A loose connection or corrosion in the bulb housing might be causing the problem, respectively. If you discover any issues with these components, be sure you have them replaced immediately.

Turn signal switch

In certain automobiles, the brake lights are powered by the same circuit as the turn signal lights, which saves on wiring costs. If this is the situation with your vehicle and the turn signal light is not functioning, it is likely that the brake lights are not functioning as well. If it is feasible to replace the cable that connects these two devices, please do so immediately. If this is the case, you may need to consult with your trusted technician. It is possible for your taillights to become inoperative for a variety of reasons, some of which may be the same as the reasons why your brake lights have stopped working.

Whenever this occurs, you may go to this guide to assist you in determining the root of the problem.

Ultimately, as a driver and car owner, it is your obligation to ensure that your brake lights and taillights are operational at all times while driving.

4 Common Brake Light Problems and How to Solve Them

Problems with the brake lights don’t have to be a source of stress. When it comes to troubleshooting brake light problems, there are some difficulties that come up time and over again, which makes it that much simpler to find out what’s wrong with your brakes when you touch the pedal. See how to resolve these four typical brake light conundrums, as well as how to avoid them in the future.

1. Burnt Out Bulb

The most common brake light problem is a burned out bulb, which is simple to understand given how common it is. When you examine how much time you spend with your foot on the brake, it is important to remember that the bulb must be lighted throughout the whole duration.

Modern automobiles have turned to LED lights that last far longer, but older vehicles still have bulbs that must be removed and replaced on a regular basis. Most of the time, it’s inexpensive and simple to do with a minimal set of tools.

2. Bad Brake Light Switch

When the brake pedal is depressed, a switch is activated, signaling to the rear-view mirror lights that it is time to turn them on and turn them on. In the course of time, analog switches become worn and dusty, which impairs their capacity to establish positive contact with the input signal and send the correct signal. In this case, replacing the switch is not a difficult task, and it is also simple for your mechanic to diagnose brake light problems such as this one. If all three brake lights go out at the same time, it’s improbable that the trio of bulbs went out at the same time as a single unit.

3. Blown Fuse

After making sure that your brake lights are working properly on both sides and that your brake light switch is in working order, the next item to check is the brake light fuse. The fuse box for your car may normally be found beneath the hood or on the kick panel in the passenger compartment. Locate the fuse box for your vehicle. Determine if the braking circuit fuse has been blown by referring to the fuse diagram found on the box’s cover (or in the handbook). If so, replace the fuse. If this has occurred, it should be replaced with a fuse of the same resistance.

4. Bad Socket

If you have a single brake light that is not working and the bulb is in fine working order, the next step is to inspect the light socket. Among the causes of brake light malfunctions are sockets with unclean or corroded connections, as well as wire that has gotten worn to the point where it is only making sporadic connections. Simply cutting the old wires and joining them together to form a new socket is all it takes to replace a socket, which is usually a rather affordable item to acquire. If you keep these suggestions in mind, the majority of brake light issues will be simple to identify and repair by yourself.

5 Reasons Why Brake Lights Not Working But Tail Lights Are

You and other drivers on the road are at risk if you are driving at night with either your brake lights or your tail lights not functioning properly. It takes a long time to notice when the brake lights are not functioning but the tail lights are, or vice versa, because they are so close together. This is due to the fact that you will not be aware of what is going on in the backseat unless someone calls your attention to it. For road safety, both the brake and tail lights are essential components.

It has the potential to cause serious accidents, particularly on dark roadways or during periods of heavy rain or snow.

The Reasons for Brake Lights Not Working but Tail Lights Are

While driving, the tail lights function normally, however using the brakes causes the rear lights to go completely dark. This is a strange problem because the tail lights function normally when driving. Occasionally, squeezing the brakes will also turn off the tail lights, and they will not come back on until you release the brakes. The following are some probable causes of brake lights not working but tail lights operating:

The Light Bulbs

The most common reason for brake lights not functioning but tail lights operating is a blown light bulb, which occurs more frequently in older vehicles. Remove the screws from the bulb lens using a screwdriver (which you can access through the trunk or see your vehicle repair manual to get the exact location). To remove the bulbs from the socket, push them down and spin them counterclockwise. It’s possible that the cause is blown out lights. If your bulbs have been discolored or if the filaments have become brittle, you should replace them.

In most European automobiles, the same bulb is used for both the taillights and the brake lights.

Fuse Box and Light Switch

You’ll need to locate the fuse box or the power distribution center to complete the task (PDC). The fuse panel will be located beneath the dashboard, while the PDC will be located under the hood. The brake light switch may also be discovered under the dashboard, and it should be checked to see if its plunger is in contact with the brake pedal arm. The brake lights will be affected if there is an issue with the fuse box or light switch. If a fuse has blown, it should be replaced with a brand new one.

Apart from that, you should try to determine what caused the blown fuse.

The Electrical Ground

If the brake light switch is operational, the next step is to look for a faulty electrical grounding (some car models have the switch provided ground). Because of a loose connection in the wire, or because of corrosion or damage to the wire ends, this might happen.

With a jumper wire, connect the light switch to a good ground and push the brake pedal to complete the circuit. If the brake light illuminates, it means that the ground connection has to be repaired. MORE INFORMATION CAN BE FOUND AT:

Check the Wiring

If all of the above-mentioned components are functioning properly, you will need to explore elsewhere for the root of the problem. It is possible that the wire from the fuse panel to the brake light switch, as well as the cabling from the switch to the bulb sockets and lights, is loose or fraying. It is possible that the connector and bulb housing have become rusted. If you discover a problem with these components, you must replace them.

Examine the Turn Signal Switch

In some car types, the brake light circuit can be found as a component of the turn signal circuit. If the brake light switch is broken or malfunctioning, the brake light will not illuminate. Examine the wiring schematic for the switch and look for the single wire that connects the brake light and turn signal switches to each other. Connect a test light to the electrical connector on the turn light switch, activate the brake light switch by squeezing the brake pedal, and then back probe the wire with the test light.

Why Won’t My Tail Lights Work When My Headlights Are On

It is possible that the tail lights will not function correctly but the brake lights will function properly. The connectors for the rear lights and the headlights are separate. As a result, one set will continue to function normally, while the other set may encounter difficulties and cease to function. Tail lights can be turned off for a variety of reasons, many of which are almost identical to the reasons why brake lights are not working but tail lights are. The following are the causes of malfunctioning rear lights:

  • Electrical problems include: blown fuses, damaged wiring, and burned out bulbs.

It is recommended that you take your car to an experienced technician if you are still unable to determine the source of the problem with your non-functional brake lights or tail lights or if you are unsure about the measures outlined above. If you are unfamiliar with the operation of a car’s mechanism, do not attempt to repair anything, whether it is a significant or little problem.
