Why My Car’s Brake Lights Won’t Work: A Troubleshooting Guide

If your car’s brake lights aren’t working, it can be a huge safety hazard. Not only are you more likely to get in an accident, but you may also get pulled over by the police. In this blog post, we will discuss some of the most common reasons why brake lights won’t work and how to troubleshoot them. We’ll also provide a few tips on how to keep your brake lights in good condition.

Top reasons car brake lights don’t work

A blown fuse

One of the most common reasons why brake lights won’t work is because of a blown fuse. If you suspect that this is the problem, the first thing you should do is check your car’s fuse box. Most cars have a diagram inside the fuse box that will show you which fuse goes to which component. If you find that the fuse for the brake lights is blown, replace it with a new one and see if that fixes the problem.

Faulty brake light switch

Another common issue is a faulty brake light switch. This switch is what tells the brake lights to come on when you press the pedal. If it’s not working properly, the brake lights won’t come on. To test whether or not the switch is the problem, you can use a multimeter to test for continuity. If there is no continuity, then the switch needs to be replaced.

Wiring issue

If your brake lights are still not working after checking the fuse and the brake light switch, it’s possible that there is an issue with the wiring. The best way to check this is to use a circuit tester. If the circuit tester does not light up when you touch it to the wires, there is an issue with the wiring and it will need to be repaired.

How to keep your brake lights in good condition

Now that you know some of the most common reasons why brake lights don’t work, let’s talk about how to keep them in good condition. One of the best things you can do is to regularly check your car’s fuse box and replace any blown fuses. You should also check the brake light switch for signs of wear and tear. If it looks like it needs to be replaced, go ahead and do that. Lastly, make sure to regularly check the wiring for any signs of damage. If you keep up with these simple maintenance tasks, your brake lights should stay in good condition and work properly when you need them.
