Brake Lights Not Working? Here’s How to Troubleshoot the Problem

Brake Light Drivers like you near Harrisburg, Mechanicsburg, and Trevose know the importance of a working brake system. However, it’s also important to have functioning brake lights—they’re your way of notifying the driver behind you whenever you’re coming to a stop.

If your brake lights aren’t working, you’ll need to know how to troubleshoot the problem. We’ll go over some scenarios below and how they can be resolved at Faulkner Auto Group.

1. Replace the Light Bulbs

Light Bulb The lightbulbs are the first thing you’ll want to check if the brake lights aren’t working. That’s because you push down on the brakes quite frequently, with the bulb being illuminated the entire time. Many newer vehicles are equipped with LED lights and consequently last much longer. However, most older models still have bulbs that can burn out more quickly.

If the light is flickering or completely burned out, they’ll need to be replaced. They can easily be popped out and changed by a service technician. The tech will then make sure to use the same type and wattage as the old ones, ensuring they’ll both work properly for a long time.

2. Check the Fuse Box and Light Switch

If the bulbs aren’t the issue, you’ll want to check the fuse box and light switch. Any time you apply the brakes, a switch gets triggered, sending a signal to the brake lights saying that it’s time to turn on. The switch can get dirty and even wear out over time. When this happens, its ability to transmit the right signal gets compromised. Therefore, you’ll want to have it replaced as soon as possible.

However, if the switch is good but the brake lights still aren’t working, there may be a blown fuse. Check the fuse box, which is usually either under the hood or on the kick panel in the passenger compartment. Look at your owner’s manual to find the location of the fuse for the brake circuit to see if it’s been blown. If it has, you’ll need to get it replaced.

3. Check All the Wiring

Certified Service Center If all the above components seem to be in good working order, some wiring in the vehicle may be to blame for the problem. You’ll want to check the wires from the fuse box to the brake light switch. Also look at the ones from the switch to the light bulb sockets. If any of them are loose or frayed, they’ll need to be replaced right away.

If the connection and bulb housing are corroded, those will need to be addressed as well. Make sure they get cleaned and changed out, as that could help troubleshoot the issue with your brake lights not working.
