The most frequent cause of brake lights working but tail lights not is an improperly placed or damaged light bulb. A blown fuse, poor wiring, or corroded sockets or plugs are other potential causes. Another potential culprit is a broken control light switch.
These are the most frequent causes, though there are other ones as well. Here is a more thorough list of the most frequent reasons why brake lights will illuminate but not the taillights.

What might make a tail light cease functioning?
Regularly checking the headlights and taillights only takes a minute, but it makes a significant impact when you’re driving. There are a number possible causes if you discover that your brake lights are functioning but your tail lights are not.
Blown fuses are the most frequent culprit for broken tail lights, followed by wiring or control switch issues. Bad light bulbs, a broken bulb socket, or a defective light sensor are some more possibilities.
Each functionality’s controls, wiring, and plugs are distinct on the taillights. Separate bulbs are utilized for turn signals, brake lights, and reverse lights, thus they contain more than simply tail lights.
These modules are divided rather than grouped together so that, in the event of a blown fuse or a broken bulb, you can still use a portion of the system.
The brake sensor, which is found underneath the brake pedal, turns on the brake lights. The switch on the left side of the steering wheel controls the turn signals. The reversing white light is turned on while the vehicle is in reverse, and the taillights are turned on by pressing the headlight switch.
Why is the tail light out?
indicators for the taillight or stoplight A light bulb or two replacements will bring order back. Some manufacturers include a text message identifying the specific out-of-service light in the instrument panel. The sign is frequently compared to eyelashes emerging from a car’s back!
Which fuse is in charge of the taillights?
The stop lamp fuse is located inside the car in the left kick panel. The brake pedal’s stop light switch is powered by a 15 amp fuse. Rear brake lights receive power from the brake light switch.
#1Bad Tail Light Fuse
When dealing with an electrical issue, especially when it comes to broken tail lights, the fuse should always be checked first.
A fuse is just a metal band enclosed in a plastic bag that is intended to blow when the current flowing through it rises to a certain level. By doing this, the electrical system’s other components are shielded from harm.
- The main fuse box under the hood is the second frequent location to find fuses. It is a big, black box with numerous wires attached to it. Its fuses are accessible once the top cover has been removed.
- One is a fuse panel located inside the car’s cabin. This is generally in the front passenger side, beneath a plastic plate underneath the dash. When the passenger side door is fully opened, you may find it on the side of the dashboard of some vehicles.
The functions of each fuse, whose cover you removed to expose them, should be listed on it. Each fuse regulates a distinct electrical component. If not, the owner’s handbook or an online search for a year, make, and model-specific schematic can be used to identify them.
Once the fuse for your tail lights has been located, you may test it with a fuse tester, which will light up if the fuse is functioning properly. Replace the fuse with one that is the same size and amperage if it doesn’t light up. On some fuses, a visual break in the metal wire inside a faulty fuse can be seen.
Why do my brake lights function but not my taillights?
A broken light bulb is the most frequent cause of brake lights that don’t work yet taillights that do. A busted fuse, a defective brake light switch, or problems with the wiring can also be to blame.
While the brake lights on your car should illuminate when you use the brakes, they don’t. Given that both lights’ connections effectively come from the same source, this is a peculiar issue. When you apply the brakes, either one light flashes more than the other or the taillights entirely turn off.
There is a cause for every problem, and every problem has a remedy. Why your brake light doesn’t function yet your taillights do is explained in more detail below:
Driving without taillights is possible.
Don’t be shocked if you are pulled over if your taillight is damaged. A broken taillight is one of the safety offenses that police are constantly looking out for. It makes it more difficult for people to see you, and if the second one burns out as well, it will be quite difficult for approaching drivers to see you at night from the back. However, you won’t necessarily receive a penalty just because you’re stopped for a faulty taillight. Although it is technically against the law to drive with a broken taillight, most police officers would likely only issue you a warning and instruct you to have it replaced as soon as possible. However, some police officers do issue citations for damaged taillights.
What symptoms indicate a blown fuse?
Take the fuse out of the holder. The fuse holder cap may occasionally need to be unscrewed using a tiny screwdriver.
Examine the fuse wire. The fuse has to be replaced if there is a clear gap in the wire or if there is a dark or metallic stain inside the glass. Follow steps 4 and 5 if you can’t tell whether the fuse is blown. Go to step 6 if it is certain that the fuse has blown.
Is the bulb used for brake and tail lights the same?
The brake lights and tail lights on many cars use the same bulb. Inside the bulb, there are two filaments: one for the brake light and one for the taillight. Additionally, some automobiles feature a unique bulb for each circuit.
How much does fixing the wiring for the tail lights cost?
For $70-$120, a technician can typically repair broken tail light wiring within an hour. If you’ve done wiring on automobiles before, you might also try doing it yourself.
What are the two main functions of your taillights?
The vehicle’s safety features include the tail lights. To enable other drivers to accurately assess the size and shape of the car, they display the rear edge of the vehicle. Additionally, they make it possible for other motorists can see the car in bad weather like rain or snow. Replace any broken tail lights right away. For having a broken tail light, you risk being stopped.
Your car’s tail lights are a crucial component of safety. To let other vehicles know where you are on the road, they are placed in the back and face backward. Depending on your preferences, you can buy many styles of tail lights.
Does the tail light have a brake light switch?
The brake light switch is a little part located next to the brake pedal that turns on the brake lights in your car.
The brake light switch activates the brake lights at the back of your car when you use the brakes. In essence, it signals to the driver in front of you that you’re going to slow down.
The brake lamp switch in contemporary vehicles also:
- influences both the Vehicle Stability Control system and the Anti-Lock Brake System (ABS)
- enables your gear selector and push-button start
Can I use my vehicle with a damaged taillight?
Driving with a damaged tail light is illegal. Two functional tail lights are a requirement for all vehicles. All tail light lenses must also be transparent. Additionally, they must come from the original automaker and look to be in good shape.
Additionally, installing dark lenses or bulbs that reduce the efficiency of tail lights is prohibited. Additionally, you should only use tail lights with U.S. Department of Transportation-approved bulbs.
