Brake light doesn’t work? (The answer is found)

If one or more of your brake lights isn’t working properly, it could mean one of three things: The brake light system fuse is blown, the brake light bulbs are burned out or the brake light wiring switch is broken. All of these issues are easy to troubleshoot.

Why do my tail lights work but not my brake lights?

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.

Is one brake light not working illegal?

By law you need to have two working brake lights. As soon as you’re aware that one of your brake lights is faulty, make sure you fit a new bulb straight away. If you’re stopped by police you could receive: A verbal warning.

How can you tell if a brake light fuse is bad?

If, however, the test light illuminates when the connection is only pressed against one side of the fuse, the fuse is faulty. If the test light fails to light at all, regardless of where it’s connected to the fuse, you definitely need to replace the fuse.

Do brake lights have a fuse?

If your lights don’t illuminate on either side and your brake light switch is good, then the next thing to check is the brake light fuse. Locate your vehicle’s fuse box, which is usually under the hood or on the kick panel inside the passenger compartment. If it has, replace it with a fuse of the same resistance.

Can you get fined for having a brake light out?

No brake lights penalty If you have a single brake light out for example and the police officer is of reasonable mind, they may simply pull you over and give you a verbal warning to get it fixed as soon as possible.

Can you drive with a brake light on?

If you’ve just started your car and notice that the brake system warning light is on, don’t run the risk of driving the vehicle. If the dashboard light remains on, it’s telling you that thre is a brake system problem that could prevent you from stopping your vehicle.

Do all 3 brake lights have to work?

Federal law mandates that all vehicles have the third brake light outfitted within the car. Additionally, the third light must be comparable to the other brake lights on the vehicle so that it is not distracting to the drivers behind the vehicle.

Can you drive a car with a broken indicator?

Technically you should not drive the car until it has been fixed.

Which fuse is for the brake 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 much does it cost to fix brake lights?

Average Cost The cost of swapping out one or both brake lights can vary widely. You can come across a wide range of prices, from $20 to $150. It will depend on your make and model and where you go to have the work done.

How much does it cost to replace a brake light switch?

A replacement brake light switch generally costs around $30 to $75, depending on the make and model of the vehicle. Getting a brake light switch fixed at a shop will add typically $80 to the repair.

Where is the brake light relay located?

A brake light switch is a small electrical relay attached to the brake pedal. It is typically installed above the brake pedal and (hopefully) activated every time your pedal is pressed.

How do you check a brake light switch?

Place the sensor on just one of the two wires and hold the brake pedal down as you do so. Then test the other wire. If power is connected and the switch is working properly, the test bulbs will illuminate. If it doesn’t light up, the brake light switch is faulty and will need to be replaced.

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

The most common reason for brake lights not functioning but tail lights operating is a blown light bulb, which is the most typical cause. Removing the bulbs from the lenses is done by removing the screws (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 in and turn them counterclockwise. One possible explanation is blown out lights. Bulbs that are discolored or whose filaments have become brittle need to be replaced immediately.

Select replacement bulbs that are the same type and wattage as the originals. When it comes to most European automobiles, the tail and brake lights are both illuminated by the same bulb. Although it contains two sets of filaments, one set can continue to function while the other is burned out.

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.

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.

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? What occurs in this situation? Also see: Why Are My Brake Lights Not Turning Off?

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.

Please continue reading.

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. Additionally, see:5 Symptoms of a Faulty BCM

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.

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.

How to Test Brake Lights

It is vital that your vehicle’s brake lights function properly. They serve as a safety element as well as a courtesy to other drivers on the road. Brake lights that are illuminated show that your vehicle is slowing down or has stopped, allowing other drivers plenty of time to slow down or stop in order to avoid colliding with you in any light or darkness. Additionally, if your brake lights do not function properly, you may be issued a traffic penalty. However, by checking your brake lights on a regular basis – a couple of times a year should enough – you can avoid all of these difficulties.

  1. If your brake lights are not working properly, you should have them repaired immediately for your own safety.
  2. Alternatively, you may have a buddy stand behind the car while you step on the brake pedal and ask him or her whether everything appears to be in order.
  3. Also, make sure all of your brake lights are working properly.
  4. Brake lights, of course, are dependent on the electrical system of a car, which is comprised of a number of switches and fuses that safeguard circuits from damage.

All of these problems are straightforward to resolve. Continue reading to discover how to detect and correct the issues.

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

There are several things you should look at to determine whether your tail lights are broken. One of the things to look for is a burned bulb, which is rather easy to check. 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 become blackened in the process of cleaning. A signal indication is also included on the automobile dashboard, which illuminates to indicate when a light bulb is not functioning correctly.

Another method is to check to see if the filament of your light is undamaged.

You will only need to replace the bulbs if it is determined that they are the source of the problem.

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.

Corrosion might also be a contributing factor to bad wiring.

As a result, dampness can cause rust to form, which can cause the entire electric circuit to malfunction.

Checking the wiring also gives you the opportunity to detect a problem with your automobile at an early stage. This keeps you well-prepared and ready to make adjustments when the time comes. 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.

  1. Following that, your tail lights should normally function properly, resulting in a safer driving experience for you.
  2. As a result, the likelihood of an accident occurring is reduced.
  3. In order to ensure that your car is in excellent working order, it is necessary to inspect it on a regular basis.
  4. It also assists you in keeping it in good condition.


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.

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. You will understand the reasons why you are experiencing these difficulties, and you will also learn about some low-cost options for dealing with them.

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.
  5. Whether or not it works may be determined by checking whether or not the tester is illuminated.
  6. 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 might result in the tail lights not operating 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. Another possibility is that a bent or damaged pin in the socket has caused the light to stop operating entirely. 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.


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!

Why is my brake light not working?

One of the most prevalent symptoms linked with a faulty brake light switch is the presence of brake lights that remain illuminated at all times.

  • Police may stop you and issue you with a warning if they find out about it (although this is quite rare).
  • Your car is not roadworthy because it lacks an abrake light on either side of the vehicle, which is required by law.
  • If the lights go out when you press the brake pedal, it is most likely due to a misaligned switch or a pedal position issue on the pedal.
  • If the lights remain on after unplugging the brake – lightswitch, a short circuit has occurred.
  • Why does my tail light illuminate but my brake light does not?

When you depress the brakes, the brake light will not illuminate if the bulb in the brake light has failed. As a result, your taillight will illuminate, but when you stop, your brake lights will not illuminate.

High-Mount Third Brake Light Not Working? Solution: Rewire.

As a result, some of you may have noticed that when you press your brake pedal, your tail lights brighten as they should, but your high-mount 3rd brake light/spoiler light does not illuminate at all. This has been a problem for me when I first purchased the prelude in 2004. It’s past time to look into it. What can we do to make the light to operate properly once more? BEFORE YOU ATTEMPT WHAT I’M ABOUT TO PRESENT, MAKE SURE YOU READ THE FOLLOWING: 1. Replace the light bulb(s) or LEDs; this is a straightforward procedure.

Replace the fuse; this is generally the source of the problem.

In addition, it may be necessary to replace your brake light switch.

It is necessary to depress the brake pedal in order for the brake lights to illuminate.

There is a good chance that there is a “short,” or that the wire is bad.:|

You must locate the “short” and remove it from the document.

Before I describe the following step, allow me to explain the “philosophy” behind why we are doing it this way.

Red and black on a white background.

It is the Red with Black wire that turns on when you turn on your lights at night to see better.

After pressing the stop pedal, the second filament illuminates, effectively making your taillights incredibly brilliant and preventing lifted vehicles from running you over (this is the Green with White wire).

The wiring for the third brake light happened to match (green with white) by chance, so we’re moving on.

All lights are turned offNight lights are turned onBrake pedal is engaged!

I’m confident that this could be used to those who have LED spoiler lights.
