Troubleshooting Brake Light Problems

Your INFINITI's brake lights alert other drivers when you're slowing down and stopping. Without properly functioning brake lights, your vehicle can be difficult to see when slowing.

Commonly, a burnt-out bulb is the cause of your brake light issues. But an inoperative brake light can be more than just a bad bulb. Learn what could be causing your brake lights to not turn off or on.


Why Are My Brake Lights Staying On?

Are your INFINITI's brake lights staying on even though you aren't pressing down on the pedal? It may be a simple fix, but other more serious problems may be the cause. Before learning how to turn off your brake lights, you need to first identify what's causing them to stay illuminated.

The brake light switch isn't working

An inoperative brake light switch can cause your brake lights to remain lit. But what does a brake light switch do? Put simply, it allows the brake pedal to switch on your brake lights. When the brake pedal is pressed, the brake light switch is triggered and sends an electrical signal to the brake lights to turn them on. But if the switch is faulty, your brake lights may not get the message to turn back off.

Something is blocking the brake pedal

Check underneath your brake pedal to ensure it's free of objects or debris. If something is caught underneath your brake pedal, it may be triggering the brake switch and keeping the brake lights illuminated.

There's an issue with the electrical system

A short in your INFINITI's electrical system may trigger your brake lights to stay on. Electrical system issues can be hard to detect. It's best to have a professional INFINITI technician locate the source of the issue and resolve the electrical system issue.

Why Are My Brake Lights Not Working?

If you suspect your brake lights aren't working, it may be tricky to know how to test your brake lights alone. Then, ask a friend to observe the brake lamps while you operate the pedal. Check the brake lights to ensure they are both lit.

One brake light is out

If only one brake light is out, it is likely a bad brake light bulb. Changing a brake light bulb typically only requires a few simple steps, but it is always best to change both bulbs at the same time to ensure the other bulb doesn't burn out shortly after.

Both brake lights are out

If both brake lights are out, there could be several issues potentially causing the problem. The brake light fuse may be open, the brake light switch may be inoperative, or there may be another electrical system issue causing the brake lights to not come on. When it comes to your brake lights not turning on, it's best not to guess. Bring your vehicle to your nearest INFINITI service center to pinpoint your brake light issue and have it professionally serviced.
