The brakes are an important part of your vehicle's operation, so ensuring the braking system, pads, and rotors are in proper working condition is essential. However, making sure the brake lights are working properly should also be a priority, especially since many rear-end collisions occur because of faulty brake lights. If you notice your brake lights are not working, here are a few common causes.

Worn Bulb

When you first notice your brake light is out, check the bulb to determine if that is the cause. In most cases, only replacing the bulb will be necessary. Carefully remove the bulb and bring it to your vehicle manufacturer or an auto part store for a replacement. If you are not sure how to remove the light cover to remove the bulb, visit an auto repair shop to have the bulb replaced efficiently.

Blown Fuse

A blown fuse is another common reason why a brake light would go out. Locating the fuse box can be tricky since each vehicle has a different fuse box location. In many vehicles, the fuse box is located in the glove compartment. However, the fuses may also be on the dashboard of the driver's side. The fuse box may also be found under the vehicle's hood.

The fuse box should have a label that shows what each fuse is for. Locate the fuse for the brake lights and replace it with the same type. If you are not sure of where the fuses are located or how to replace the fuses properly, visit an auto repair shop for assistance. This will ensure the appropriate fuse is replaced.

Electrical Issue

Replacing a bulb or a fuse are simple fixes for a brake light that is out. Unfortunately, there are instances where the problem could stem from a more involved issue. For example, if there is an electrical issue, there may be another problem other than the faulty brake light. Damaged electrical wiring could be the cause of your blown brake light. If wiring is the problem, you may notice other lights are flickering out completely.

A defective bulb socket could also be affecting the function of your brake lights. Remove the bulb and inspect the actual socket. If you notice discoloration or rust, the socket has started to corrode and will not allow the light to work. Replacing the entire socket will be the only way to restore your brake light.
