Most total headlight failures are caused by a bad component like a fuse, relay, or module. Wiring problems can also cause both headlights to stop working. The cause: A burned out bulb, or a problem with the high beam switch or relay. The fix: Replace the bulb, switch, or relay.
How do you fix headlights that won’t turn on?
My Headlights Won’t Work
- Inspect the headlights to make sure the filaments are not broken.
- Check the headlight fuses in the car’s fuse box.
- Check the connectors, wiring harness and socket into which the headlight bulbs are plugged.
- Pull out the headlight relay if the headlights still do not work.
Can a blown fuse cause headlights to go out?
If a headlight fuse blows, it could cause the headlights to stop working. Most headlight systems are also designed with a relay that switches the power between low beam and high beam headlights. If this relay goes bad, it could allow power to the high beams, but not the low beams.
Is there a fuse for your headlights?
Like all electrical systems, the headlights in your vehicle have a fuse in the circuit to prevent too much electricity from reaching the bulb. There will also be a headlight relay that switches power from the low beams to the high beams.
How much does it cost to replace a headlight relay?
Replacing a headlight relay is a DIY-friendly repair that you can usually do yourself. A headlight relay generally costs less than $30 for just the part itself. Of course, the exact cost will vary depending on a variety of factors, such as the year, make, and model of your vehicle.
What do you do when your headlights go out?
Headlight Failure
- First, try your dimmer switch. Often that will turn them back on again.
- Try the headlight switch a few times. If that does not work, use your parking lights, hazard lights, or turn signals.
- Pull off the road as soon as you can and leave your hazard lights on so that other cars can see you.
Why would both headlights go out?
Most total headlight failures are caused by a bad component like a fuse, relay, or module. Wiring problems can also cause both headlights to stop working. The cause: A burned out bulb, or a problem with the high beam switch or relay. The fix: Replace the bulb, switch, or relay.
Where is the headlamp fuse located?
The front of the dash panel has a fuse panel on it.
What causes both headlights to stop working?
Solution: If both headlights aren’t working, it’s unlikely that a bulb is at fault. The likely cause is a fuse, headlight relay, headlight switch, dimmer switch or a wiring fault. About the only cause that is an easy fix is a blown fuse.
How much does it cost to fix a wiring problem in a headlight?
The wiring may be damaged over a period of time. It can cost you $100 per hour. The reason behind the problem may be a faulty headlight switch. Often times, if the headlight works only on high beam or low beam, the dimmer switch may have broken.
How can you tell if a headlight bulb is bad?
One of the first symptoms of a bad or failing headlight bulb is dim headlights. Over time headlight bulbs can wear out and begin to shine noticeably dimmer than when they were new. A dim headlight will not provide proper illumination and is also usually a sign that the bulb is approaching the end of its service life.
Will AutoZone change my headlight?
If simply a headlight needs to be replaced, an experienced AutoZone employee should be able to handle it with ease. AutoZone does not provide mechanic services; thus, no disassembly should be done. However, they can change headlight bulbs in some cases.
How do you check a headlight relay?
Open the hood, locate the fuse box with the headlight relay or relays, and open it. Put your ear close to the relay and listen. Alternately, you can wedge the handle of a long screwdriver into your ear, and touch the screwdriver point to the relay. You can hear the relay click though the screwdriver like a stethoscope.

Damaged Relay
In the lighting system, a relay is a component that is responsible for supplying electricity to the headlights. Just like the other components of the headlamp, the relay has the potential to malfunction. The car’s headlights will not illuminate in this situation. If you do chance to face an issue with the relay, you should try changing it and checking it once again.
When One Headlight Does Not Function
When both headlights are not working, it is evident what to do. The options listed above are straightforward. If, on the other hand, only one headlight is faulty, the cause may be quite different. For example, if the filament of a certain light bulb has burned out and has to be changed, When you notice that the bulb has become a little bleached or discolored, it is an indication that the bulb needs to be replaced. If this is the case, replacing the old bulb should result in the headlight operating properly once again.
With these simpleMaintenance Tips, you can take care of your automobile on your own.
Examining each component one by one may be the most effective option since it allows you to discover which component has failed.
Other than the bulb itself, make sure the headlight switch, wiring, module, or fuse are all working properly. It is important to note that if the bulb seems dark or bleach in appearance, the headlights will not function. (Image courtesy of latercera)
The Last Words
If you have any knowledge of the engine system, you will find that repairing the headlight is a reasonably simple task to complete. The specialists, on the other hand, should be consulted if you are an amateur or have never dealt with the complexities of a car before. Those are some of the remedies that may be used when the headlights will not turn on, and we hope you find them to be useful.

This article will address the most common reasons why headlights cease working as well as how to diagnose the problem. Eventually, knowing these things will assist you in figuring out how to deal with an unpleasant scenario so that you may still have an enjoyable road trip. While driving, headlights can help us to stay as safe as possible on the road.
However, no matter how well-prepared you are, headlights can sometimes cause some unanticipated troubles with your vehicle.
What is causing my headlights to not turn on?
Reasons WhyHeadlightsAre Not Turning On
It’s something that many of us have experienced. It is nighttime, and you are driving through the middle of the road under a night sky. It was then that your car’s headlights quit working all of a sudden! A variety of factors might contribute to your headlights not turning on. We will go through some of the most prevalent reasons for this and how you should prepare for it. One of the most common reasons why headlights fail to come on is the likelihood of burnt wires in the circuit. These cables are responsible for connecting the headlights to the vehicle’s primary battery.
- What to do is as follows: Examine the cables that link the components.
- If your car’s headlights still won’t turn on, your only other alternative is to take it to a nearby repair or ask a professional to come out and assist you.
- What to do is as follows: Removing the current relay and replacing it with a new relay are the only options.
- What happened?
- What to do is as follows: Examine this failure by removing the component from the system.
There are a variety of reasons why consumers may not be able to detect the failure of a defective headlight switch in their vehicle. If this is the case, you should turn off the headlights. Only the fuse in the headlight should be removed, or the battery should be disconnected.
One Headlight (LED, Xenon orHalogen) Doesn’t Work
A faulty ground connection, a faulty ignitor, a wire harness flaw at the ignitor, a loose bulb, a tarnished bulb socket, or a faulty headlight bulb might all be the source of the problem. Visually inspect it to make sure it’s correct. Typically, a burnt-out bulb is bleached to restore its brightness. The filament within the bulb has most likely been burned, as seen by the filament’s loose fragments in the bulb or a gap within the filament itself. However, the bulb is in excellent shape! It’s possible that the problem is caused by a damaged wire or a faulty switch.
BothHeadlightsDon’t Work
Almost certainly, the cause of this particular failure is a lack of voltage in the system. It’s possible that this is due to a broken headlamp relay, headlight switch, wiring problem, dimmer switch, module, or fuse, among other things. It is preferable to check and inspect the primary fuse for the headlight circuit before starting the engine. If the fuse explodes instantaneously, you’ll notice a short in the headlight circuit. However, if the fuse is in better condition and there is electricity flowing through your car’s headlights, the module is most likely the source of the problem.
As a result, it is highly suggested that you seek expert assistance.

Headlights Not Working? Try These Fixes
Although headlight technology isn’t very complicated, there are a variety of ways in which they might fail in different situations. So, if you discover that your headlights have suddenly stopped working, it’s critical to identify the sort of malfunction you’re dealing with and proceed accordingly. You’ll need to determine what kind of issue you’re dealing with in order to choose the proper troubleshooting procedure to use.
To begin, it may be quite helpful to determine whether or not both, or simply one, of your headlights have failed, as well as whether or not the high or low beam mode is still operable in this situation.
Common Situations and Fixes For Headlights Not Working
Luyi Wang is a freelance journalist. An electrical fault or a physical problem with the bulbs themselves are the most common causes of headlight failure. In order to get to the bottom of the matter as fast as possible, it’s critical to make a detailed note of the specific sort of failure you’ve experienced. You may use the following information to narrow down a solution based on which bulbs have ceased operating and under what conditions they have stopped working:
- The reason is generally a burned out light bulb
- However, there are other possibilities. The solution is simple: replace the bulb. If it still doesn’t work, look for an issue with the wiring or the fuse.
- Aside from the headlights themselves, additional components of high intensity discharge (HID) headlights might fail. Neither of the headlights are operational.
- Aside from the headlights themselves, additional components of high intensity discharge (HID) headlights might malfunction. No light comes on from either of the headlights.
- Although bulbs seldom burn out at the same time, it is nevertheless vital to rule out the possibility of a group failure by checking for power. Faulty components such as a fuse, relay, or module are responsible for the majority of complete headlamp failures. Wiring issues might sometimes cause both headlights to cease operating at the same time. High beam headlights are not working, and low beam headlights are not working
- The problem is caused by a burned-out bulb or by a fault with the high beam switch or relay. The solution is simple: replace the bulb, switch, or relay.
- If only one bulb fails to operate in either the high beam mode or the low beam mode, it is possible that the bulb is the problem. The majority of headlight failures that affect only the high or low beams are caused by a faulty relay or a malfunctioning high beam control switch. The headlights are functional, however they appear dim. The reason for this might be due to foggy lenses, worn out bulbs, or a problem with the charging system. Cleaning the lenses, replacing the bulbs, or repairing the charging system are all options for repair. If your headlights are always dim, the issue might be due to hazy lenses or worn out bulbs. If your headlights appear to dim under certain conditions, there may be a problem with your charging system. Other types of headlight difficulties are caused by a mix of defective bulbs, wiring or relay problems, and bad switches
- These are described below.
How Do Headlights Work?
Most headlight systems are rather easy, consisting of a few fundamental components such as the bulbs, a relay, a fuse, and a switch, among others. There are variants on this fundamental theme, such as daytime running lights, adaptive headlights, and other minor details such as fog lights, but the underlying concept remains the same: to illuminate the road ahead. When you turn on your headlights, the switch triggers a relay, which then turns on your lights. That relay, in turn, is responsible for establishing an electrical connection between your headlight lights and the battery, among other things.
A high beam control is similar to a headlight switch in that it operates a relay in order to deliver electricity to the high beams.
With two filament headlamp capsules, this physically transfers electricity to the high beam filament, which is a very good thing!
In addition, by examining the manner in which they failed, you can typically determine where the ideal spot to begin troubleshooting would be.
Fix It Yourself or Take It to a Mechanic?
Although replacing a burned-out headlight is normally a simple task, there are several instances in which you may want to see a professional technician. Consider sending your automobile to a professional during daytime hours if you do not have access to some fundamental autotools and basic autodiagnostic autotools on hand. if you do take your car to a shop, they’ll most likely begin by performing a visual inspection of the headlight system, checking your fuses, and inspecting the switch and relays, among other things.
Diagnostic procedures that a skilled technician will really undertake are similar to the ones mentioned in the next section.
Fixing One Bad Headlight
When one headlight quits working while the other is still operational, the problem is almost often caused by a burned-out bulb in the first place. It is unlikely that both of your headlight bulbs would fail at the same time, even if both of them have been subjected to the exact same environmental circumstances. In fact, it’s rather usual for one bulb to go out first, followed by the other. You should inspect the electrical connector for evidence of damage or corrosion before writing off your headlight bulb as faulty.
It is still necessary to investigate more in order to determine how it became loose in the first place.
Regular halogen capsules have a shelf life of between 500 and 1,000 hours on average.
If there is any water or condensation inside the headlight assembly, that is a simple item to search for.
When this occurs, the operational lifespan of your headlight capsule will be substantially reduced, and the only way to remedy the situation is to replace the entire headlamp assembly with another one.
What to Do When Both Headlights Stop Working
When both headlights fail to illuminate at the same moment, it is unlikely that the bulbs are to blame. Only in rare cases does this not occur, such as when one headlight dies first and remains undiscovered for a period of time before the other bulb fails as well. If you have a suspicion that the bulbs may be faulty and you have access to a voltmeter, you may wish to begin the troubleshooting approach by testing for power at the headlights to begin with. Using the headlight switch, connect the negative lead on your meter to a known good ground, then connect the positive lead to each of the headlight connection terminals is the best method to accomplish this.
After that, you can try to activate your high beams, which should result in a different terminal indicating battery voltage than the one you started with.
Testing Fuses, Relays, Switches, and Other Headlight Circuit Components
Most of the time, when both headlights fail at the same time, it is not the bulbs’ issue. Only in rare cases does this not occur, such as when one headlight burns out first and remains undiscovered for a period of time before the other bulb fails as well. You may wish to begin the troubleshooting approach by testing for power at the headlights, if you have reason to believe the bulbs are faulty and you have a voltmeter. Using the headlight switch, connect the negative lead on your meter to a known good ground, then connect the positive lead to each of the headlight connection terminals is the most effective method of doing so.
After that, you may try to activate your high beams, which should result in a different terminal indicating battery voltage from the one that was previously shown.
How to Fix Low or High Beam Headlights Not Working
Many of the same issues that might cause headlights to stop operating completely can also cause just the low or high beams to stop working. If you discover that just one bulb is affected when the high beams are turned on, but the other remains operational, it is likely that the high beam filament has been burned out in the first bulb, as previously stated. The same holds true if one bulb was previously used on high beams but is now used on low beams. The failure of high or low beams is almost often caused by a relay or switch malfunction, and the troubleshooting process is quite similar to the one described above.
Assuming you’ve found the high beam relay and discovered that it is not receiving power when the high beam switch or dimmer switch is triggered, the fault is most likely with that switch or with the wiring itself.
This problem can be caused by a loose stalk-type switch in certain situations, but it is more typical to find that the switch has failed completely.
What Causes Headlights to Seem Dim?
The majority of the time, when headlights fail to function, they fail completely. There are several scenarios in which you may notice that your headlights are not as bright as you would expect them to be, but the underlying cause may or may not be linked to the headlights in the first place. It’s possible that a number of reasons are at play if your headlights are consistently dim or don’t appear to be properly illuminating the road. The first is that headlights do, in fact, lose their brilliance as they get older.
Dirty, foggy, or oxidized headlight lenses can also cause problems by obstructing part of the light that is sent through them.
While it is occasionally feasible to drill a small hole into a headlight assembly in order to drain off water, this may not be a long-term solution in some situations.
Headlight reconditioning can frequently be used to repair oxidation on the lens covers of headlights.
Headlights and Electrical System Issues
If your headlights only appear dim when the vehicle is idle and the brightness appears to alter in response to the engine’s revolutions per minute (RPM), the problem may be related to the electrical system. The most likely reason is a defective alternator or a loose belt. If you notice that your battery voltage is below 13V when the engine is running, then you’ll want to check out the charging system before you worry about the headlights. Even though the charging system appears to be functioning well, it may not be able to keep up with the demands of the electrical system in some instances.
Dashboard and headlight illumination are generally the first signs of a malfunctioning charging system, which can occur when the charging system cannot keep up with the needs of aftermarket components such as amplifiers for your car.
Additional Problems With HID Headlights
Traditional halogen headlamp failures are normally rather basic, but when dealing with xenon or high-intensity discharge (HID) headlights, things can get a little more difficult. Although it is conceivable for a HID bulb to burn out, there are a number of additional potential sites of failure that you should be aware of before proceeding. It’s possible that the bulb has burned out, or that the problem is related to a defective ignitor or a wiring problem. The quickest and most accurate approach to determine whether or not your HID headlight capsule is defective is to carefully remove both bulbs and replace the one that does not function with the one that works.
It’s vital to remember that if you do decide to switch the bulbs to rule out a problem with the ignitor or wiring harness, you must avoid touching the capsule’s glass envelope.
It is not recommended that you switch the bulbs unless you are completely sure in your abilities to do so without contaminating the glass envelope. You run the risk of destroying or significantly shortening the life of your excellent bulb.
4 Reasons Your Headlights Aren’t Working
Nobody has to remind you how vital headlights are, or how hazardous it may be to drive with those that are not working properly. There are a variety of factors that might contribute to this issue, but one thing stays constant: it is an urgent situation that must be handled promptly. Delaying the maintenance of headlights is dangerous and unlawful, even if you only drive during the daytime. Check out the four possible causes listed below, and then arrange your service appointment as soon as possible.
4. Blown Fuse
When you experience an electrical problem, such as non-operational headlights, one of the first things you should do is check the fuse for the faulty component. Find the fuse for your low beam headlights in your Toyota owner’s handbook; remove it and check it. Your Toyota owner’s manual will contain a list of what each fuse is responsible for. If the fuse has been burned out, try replacing it with a functional fuse of the same amperage and seeing if it solves the problem. Otherwise, it is possible that one of these other problems is at fault.
3. Wiring Problem
The wiring in your automobile is complicated, and defective wiring might result in the inability to operate the headlights. In reality, wiring issues might potentially result in a blown fuse, as fuses burn out when an excessive amount of electricity is sent through a system. If it’s a one-time problem, the fuse may only need to be replaced once. However, if the problem is caused by a faulty wire connection, the new fuse will not be effective. It is advised that you leave the diagnosis of your car to the professionals due to the intricacy of the wiring in your vehicle.
2. Damaged Relay
Each time you turn on a light switch in your home, the switch completes a circuit and causes the lights to illuminate. Things function a little differently in your automobile. Although you flip the switch, the circuit is not completely completed by the switch. Instead, it transfers a little amount of energy to a relay, which then completes the circuit. If the relay has failed, it is possible that it is receiving power from the switch but is unable to complete the circuit. In these types of situations, a new relay may be necessary.
If one of these relays fails, it is possible that the other will continue to function.
1. Burned-Out Bulbs
If the headlights on both sides of your vehicle are not working, you might not guess that the problem is due to burned-out bulbs. After all, bulbs don’t normally go out at the same time as one another. Although it is a less prevalent reason than you might expect, it is nonetheless a significant one. This is due to the fact that today’s headlights are substantially brighter. It is possible that you will not notice that one of the bulbs has burned out since the other bulb is giving sufficient illumination.
Troubleshooting Common Headlight Problems
No matter if you’re driving home from a late night at work or being caught in a thunderstorm while dropping the kids off at school, you rely on your headlights to guide you through the night. Your safety and the safety of your passengers are jeopardized when your headlights are not operating correctly. Not only are you unable to see, but other drivers are also unable to see you, putting you and your passengers in danger. This troubleshooting guide can assist you if you are experiencing issues with your headlights.
- Information about the background: Because they are simple, cost effective, and provide brilliant light, halogen headlight bulbs are a common light source for automobile headlights.
- If you drive 12,000 to 15,000 miles per year, you may need to change a bulb every 5 to 6 years, depending on how much of your driving is done at night and how many miles you drive.
- In most cases, the socket that secures the bulb in the headlight housing twists into the rear of the housing, and turning the socket and bulb a quarter turn counterclockwise will allow you to take them out of the housing.
- Precaution: Do not place your fingers on the glass of the new halogen bulb to avoid damaging it.
- Replace the socket in the headlight housing after putting the new bulb into the socket with a cloth or while wearing gloves.
- If the bulb is operational, simply change the socket and you’re good to go.
- Information about the background: High-intensity discharge (HID) headlight bulbs are arc lamps that seem similar to a neon sign in appearance.
HIDs are more energy efficient than halogen lights, allowing them to provide more light while using less energy.
Optional replacement of the bulb and the ignitor in some HID headlights is necessary because they are packaged together.
If this is the case, insert a known-good bulb/ignitor into the socket of the burned-out headlamp and turn it on.
When using HID headlights in other applications, different bulbs and ignitors are used, and it’s required to conduct a bit more detective work to figure out which one has to be replaced.
If the “good” bulb does not illuminate, you will need to use a known “good” ignitor module and connect it to the socket from the burned-out headlight that now contains the “good” bulb, as shown in the diagram.
Unless the bulb continues to fail to illuminate, the problem is most likely due to a malfunctioning wiring harness or a corroded bulb socket, and it is necessary to seek professional assistance.
If neither of your headlights are working, it’s time to start looking for answers.
The most likely reason is a blown fuse, a blown headlight relay, a blown headlight switch, a blown dimmer switch, or a blown wire harness.
Consult your owner’s handbook to determine where the primary fuse for the headlight circuit is located, and then replace that fuse with another fuse with the same amp rating.

Common Reasons Your Headlights Stop Working — State Street Auto Repair
The majority of headlight systems are uncomplicated, consisting of a few basic components such as the bulbs, a relay, a fuse, and a switch, among other things. The core concept remains the same, albeit there are some little alterations, such as the addition of daytime running lights, adaptive headlights, or other minor details such as fog lights, but the overall concept remains the same. When you turn on your headlights, the switch triggers a relay, which then turns on your lights. That relay, in turn, is responsible for establishing an electrical connection between your headlight lights and the battery, among other things.
Your headlights will not function correctly if any of these components cease to function properly.
When your headlights quit working, it’s either because of an electrical problem or because of a physical fault with the bulbs.
You may use the following information to narrow down a solution based on which bulbs have ceased operating and under what conditions they have stopped working:
One headlight doesn’t work
Most of the time, this is caused by a burned-out light bulb. You have the option of replacing the bulb. If it still doesn’t work, look for an issue with the wiring or the fuse.
Neither of the headlights work
It is fair to assume that this is the result of either burned out bulbs or a problem with the power or ground. Check for power and ground, then make any required adjustments. If this is the case, the bulbs should be replaced. Although bulbs seldom burn out at the same time, it is nevertheless vital to rule out the possibility of a group failure by checking for power. Faulty components such as a fuse, relay, or module are responsible for the majority of complete headlamp failures. Problems with the wiring might also result in both headlights not operating at the same time.
High beam headlights don’t work or low beams don’t work
A blown bulb, a malfunctioning high beam switch, or a faulty relay might all be to blame in this situation. You’ll need to swap out the bulb, switch, or relay to fix the problem. If only one bulb fails to operate in either the high beam mode or the low beam mode, it is possible that the bulb is the problem. The majority of headlight failures that affect only the high or low beams are caused by a faulty relay or the high beam control switch.
Headlights work but seem dim
This might be caused by hazy lenses, worn out bulbs, or a problem with the charging system. Cleaning the lenses, replacing the bulbs, or repairing the charging system are all possible options. If your headlights are always dim, the issue might be due to hazy lenses or worn out bulbs. If your headlights appear to dim under certain conditions, it is possible that there is a problem with the charging system. Although replacing a burned-out headlight is normally a simple task, there are several instances in which you may want to bring your vehicle to State Street Auto Repair for assistance.

5 Reasons Car High Beams Work but Low Beams Don’t in Columbus, OH
The headlights on your car are responsible for illuminating the road ahead of you at night. It is possible that your headlights may be critical to your safety during the day since they will make your car more visible to other drivers. It’s one of the more typical difficulties we find with headlight systems when the usual low beams cease operating, but the high beams continue to operate well. Below, we explore five possible causes for this to occur, with the most prevalent explanation ranking first on our list of possible causes.
Over 120 years have passed since the Byers family began operating in the transportation industry; thus, we want to ensure that you are completely satisfied with the service we give.
5. The Headlight Socket is Corroded
A bulb is used as the headlight on many automobiles, and it is inserted into a socket, which is where electrical connections are formed. A faulty connection, a poor ground in the circuit, or moisture getting into the headlight socket can all cause the headlight socket to get corroded and eventually fail. This may initially result in a headlight that flashes in and out, or it may cause the bulb to go out completely and not return.
4. Headlight Wiring is Compromised
Although automotive wiring is intended to be long-lasting, it may also serve as a tempting chew toy for mice. Perhaps the previous owner of the car felt confident enough to rewire the headlights, and as a result, they haven’t functioned properly since. If you believe that the wiring is the source of your headlight problems, we recommend that you have it checked thoroughly by a trained technician at your nearest authorized dealer as soon as possible.
3. Headlight Switch is Broken
Normally, we don’t see this issue with Subaru vehicles; however, a faulty headlight switch might be a problem. For example, it may become stuck in the high beam setting, or the switch could become worn out and cease to turn on the headlights at all. If the switch is faulty, replacing it with a new OEM headlight switch is usually the most cost-effective solution.
2. Headlight Fuse or Relay is Bad
The headlights in your car, like other electrical systems, have a fuse built into the circuit to prevent an excessive amount of power from reaching the bulb. There will also be a headlight relay, which will transfer the power from the low beams to the high beams while the vehicle is in reverse. If the fuse fails, you will most likely not be able to operate your headlights at all. If the relay fails, you will not be able to switch between high and low beams, which is a major inconvenience.
4 Reasons Your Car’s Low Beam Headlights Aren’t Working
20th of May, 2019 It should go without saying that driving without working headlights is not a good idea. If your Subaru’s low beams aren’t working, it may seem like a smart idea to switch to the high beams—but doing so can be harmful as well.
If the high beams function well but the low beams do not, there are a variety of probable reasons for this. We’ve compiled a list of four of the most often encountered.
4. Burned-Out Bulbs
Modern headlight bulbs have the potential to be far brighter than those used in the past. In the event that one of your headlights fails, you may not be aware of it until you are driving about with only one bright headlight. If the second one goes out, on the other hand, you’ll know about it immediately away!
3. A Blown Fuse
Modern headlight bulbs are capable of producing far more light than their predecessors. One of your headlights may have failed without your knowledge; as a result, you may be driving about with only one lighted headlight on. The second one, on the other hand, will burn out, and you’ll know it immediately.
2. Problematic Wiring
Faulty wiring can result in a blown fuse, but it can also present itself in a variety of different ways. Even if the fuse is still in good working order, an issue with the wiring in your Subaru might cause the headlights to fail to illuminate. Because the wiring is so complicated, it’s better to leave these repairs to the professionals who are experienced in this field.
4 Reasons Your High Beams Aren’t Working
Driving without your high lights (sometimes known as the brights) isn’t exactly a bright idea, especially on rural roads where visibility is limited. Low-beams are typically sufficient to aid vision in urban areas without blinding others, while high-beams are necessary for better visibility in rural and suburban areas. If your car’s high lights aren’t operating properly, you may want to slow down throughout the night when the road becomes twisting to avoid hitting any unidentified objects on the roadside.
In our service facility, our highly qualified specialists may do an analysis of your electrical system, fix a defective switch, or just replace a burned-out headlight bulb.
Reason4: Bad Automatic High Beam Sensor
Manual high beams are found in the majority of automobiles on the road today; however, automated high beam technology is becoming increasingly common in newer automobiles. The automobile uses sophisticated sensors to monitor the amount of ambient light in the environment and to identify impending traffic. This feature automatically turns on your high-beams to optimize visibility when appropriate, and then shuts them off to avoid blinding traffic coming from the other direction. If one of these sensors breaks, the automated high beams may be unable to function properly anymore.
Reason3: Burned Out Headlamp Bulbs
When it comes to LED technology, which is gradually replacing typical halogen lights, one of the advantages is that LEDs do not actually burn out. They’ll die eventually, but it won’t be until the automobile has completed its whole service life that they do so. While you may not need to change all of the headlight bulbs in your car, if it is still equipped with standard halogen lights, you may need to do so from time to time. Because it is extremely improbable that two bulbs would burn out at the same time, if your brights aren’t working at all, it is most likely that the bulbs are burned out.
Simply replace them with new ones, and you’ll be good to go – but be sure to get this surgery done by a professional to ensure a successful outcome. Headlamp bulbs that have been improperly placed might become ineffective sooner than expected.
Reason2: Bad Headlight Switch
If the bulbs are in good condition, it may be required to inspect all of the electrical components that are responsible for the operation of your lights – including the high beam switch. Even the physical switch that you use to activate your high beams can malfunction, preventing you from being able to turn on your brights when you need to. Car electrical problems are best addressed by trained dealership personnel, such as those who work at the Carter Subaru repair center in Ballard, Washington.
Reason1: Blown Fuses or Bad Replays
The most frequent cause for your brights to quit working is a blown fuse or a broken relay, which are both very common. A fuse box is located under the hood of your vehicle and contains a number of fuses and relays that are connected to various electrical components throughout your vehicle. You will need to replace the high beam fuse in this case, and the circuit will also need to be checked for faults. Alternatively, it might be a faulty relay. If the headlight relay has failed, it is possible that the vehicle may not respond when you attempt to turn on the high lights.
When do I have to have my headlights turned on in Vermont?

Rules for night driving in Vermont
An experienced motorist can adhere to all applicable traffic laws and yet be caught off guard by unexpected surprises that appear out of thin air at a road’s edge during nighttime driving. When driving after dark, having your headlights on at the appropriate times – not to mention correctly focused – will be quite vital for your safety. The following are some crucial considerations to keep in mind when you’re driving after the sun has set.
- Drivers in the state of Vermont are required to turn on their headlights 30 minutes before sunrise and 30 minutes before sunset on a daily basis. This is the time of year when animals will be more active and may cross the road. In the perspective of Vermont’s driving rules, simply having your vehicle’s parking lights switched on does not constitute turning on your headlights. Drivers should turn on their headlights when traveling in adverse weather, according to the Vermont Department of Motor Vehicles, even if it is not required.
Do I have to have my headlights on during the day?
In accordance with the official Vermont Department of Motor Vehicles website, drivers are not obliged to have their headlights turned on during the daylight hours.
Driving with your low lights on during the day, according to research conducted by the state DMV, can lower the likelihood of vehicle crashes by as much as 20 percent, according to the state DMV.
Are daytime running lights enough?
While there have been significant developments in the usage of LED technology in daytime running lights, the Vermont DMV still recommends that you utilize your low beams (at the very least) when you are driving. If you would like to witness firsthand how any of the new Toyota cars presently available at Heritage Toyota are assisting people in becoming better drivers, please book a test drive with one of our sales experts today.
Both Headlights won’t Turn off and now won’t Turn on.
Here’s a quick and easy technique to diagnose this issue without the use of a multimeter. Take a look at the circuit diagram. It is important to note that the electricity is dedicated to the headlights at all times. Then, in two cases, the headlights are turned on by supplying ground for the circuit. Ground is provided by either the door-lock relay or the headlight switch. Let’s have a look at the first scenario: It should be noted that the door-lock relay triggers the headlight relay, which links the ground side of the circuit and turns on the headlights.
- Listed below is what occurs when you turn on your headlight switch: The headlights are now again powered on at all times.
- When the headlight switch is turned to the low ON position, a path to ground is created for the passage of electricity, and the headlights turn on.
- Check to see if the headlight switch breaks the circuit when in the OFF position!
- If they do, then you know that something is wrong with the headlight switch, because the switch is intended to terminate the circuit when the light is turned off.
- The OFF position indicates that there is no continuity, infinite resistance, or an open circuit.
- Following the completion of this second test with a multimeter, you will obtain the following results: The OFF state represents continuity, zero resistance, and a closed circuit.
- When the headlight switch is switched to the OFF position, the headlight circuit is not disconnected!
- 5-minute troubleshooting, no money lost rushing to auto-parts stores or junkyards to randomly sling pile of components at car, hoping/wishing one of them is the problem, and no time wasted waiting for one of those to be the problem.
- For the sole purpose of flashing headlights while opening and locking doors.
That is why the switch fails, especially if you use higher-wattage bulbs than the ones that came with the switch. All of the current flowing through the headlight switch burns or welds the metal contacts together, preventing them from disengaging when the switch is turned off.
Car Headlight Replacement 101
Drivers’ ability to see on the road becomes significantly more difficult when the sun sets and it becomes dark outdoors. Fortunately, all cars are equipped with headlights, which aid in the illumination of the road ahead. Just like any other light, they might get dim or completely dark over time, depending on usage. It is possible that driving around with only one headlight will put you and other drivers in danger, as well as putting you at risk of receiving a traffic citation. When it comes to your car’s headlights, you may be in the dark.
- What is the number of lights that are not working?
- Having two headlights go out simultaneously, though it may appear to be coincidence, is not frequent and will require more investigation to determine the cause.
- If your lights haven’t lasted exactly that long, there may be a problem with them that has to be addressed in order to discover why they haven’t lasted any longer.
- Check the connections to make sure there isn’t any damage or visible corrosion before proceeding.
- However, it is recommended that you consult with an expert to identify what caused the connection to become loose and to have it fixed as soon as possible.
- The entire headlamp assembly will be need to be replaced if this occurs.
- The failure might be caused by a faulty headlamp relay, module, main switch, or fuse, among other things.
So, what does it mean if my lights are dimmer than usual?
If the lights tend to fade when the engine is idle and the brightness reduces as the engine’s RPMs increase, this might signal a problem with the vehicle’s electrical system.
A faulty connection or ground might also result in a feeble light being produced.
Over time, the UV rays from the sun damage the plastic cover that protects the headlights, causing the lights to become dull and dim in appearance and their brightness to diminish.
Headlights are being replaced.
Driving with one or both headlights turned off is not only unsafe, but it may also be against the law in your state, depending on the regulations in effect.
Motorcycles are exempt from this requirement.
You may only be required to present proof of rectification and pay a minor court cost if you are found to have violated the law in many instances.
Is It Possible for Me to Replace Them?
There are some repairs, on the other hand, that are better left to the experts.
When it comes to Xenon, LED, or entire headlight assemblies, it is better to leave it to the specialists who have been educated in the appropriate handling, installation, and maintenance of these types of lights.
While they may not go out at the same time, it is likely that one will not survive as long as the other. To replace a headlight bulb in your automobile, follow these instructions, which are highly recommended:
- Open the hood of your car. The hood of the car, believe it or not, is the most convenient method to get access to the headlight. It is not recommended that you attempt to remove the outer light cover. Remove the electrical connector that protrudes from the rear of the headlamp and set it aside. Please keep in mind that some cars require the entire component to be removed. Screws or mounting pins are commonly used to secure assemblies in place. Remove the screws carefully since they may be difficult to access depending on their location
- This may take a significant amount of time. Gently twisting the bulb to the left will help you locate and remove the bulb. Install the replacement bulb while wearing gloves or using a tissue or towel to protect your hands. Take extra care not to touch the bulb or the assembly while it is in operation. Oil or smudges left behind by your fingers can produce a hot spot on the glass, leading halogen bulbs to burn out more quickly than they otherwise would. Reconnect the electrical connection and turn on the light to check the bulb. Steps 2 and 3 should be repeated for the other headlight.
Is It Possible to Replace My High Beams? When going on roads with little to no illumination, having high beams is a fantastic feature to have on your vehicle. While driving, using your high lights provides you with a greater and broader field of vision. Most current automobiles are equipped with headlights that have two settings, including a low setting and a high beam setting, so you won’t have to replace both headlights at the same time. Cars used to have separate bulbs for the high and low headlights in the past, but that has changed.
Please keep in mind that these bulbs are not interchangeable.
If your car has two components, one on each side of the vehicle, it is likely that it has separate high and low beam systems.
The dual filament bulb is utilized to run both the low and high beams.
