Here’s Why Your Brake Lights Won’t Turn Off | McKinney, TX

Brake lights serve as a signal to other drivers when you are — and aren’t — applying pressure to your brakes. This is one of the most crucial technologies responsible for helping to prevent rear-end collisions.

To do so, though, brake lights must be functioning properly. If a brake light goes out, you just simply need to replace the bulb. But, what if your brake lights are always on, even when you are not pressing down on the brake pedal?

This can be dangerous, as other drivers will soon realize that your brake lights aren’t truly signaling when you are slowing or stopping — and they’ll eventually stop paying attention to your brake lights altogether.

If your brake lights are out, we recommend bringing your vehicle in for service here at El Dorado Mazda in McKinney, Texas, so we can diagnose and fix the issue. Or, if you’re car-savvy, try to resolve the problem at home by checking for these common causes.

The Brake Pedal Is Stuck

Sometimes, brake pedals might be slightly pressed — just enough that the lights are engaged. While in park, slam down on the brakes a couple of times to see if this fixes the issue.

The Pedal Stop Has Worn Off

Pedal stops are installed on both the accelerator and the brake pedal. These prevent your foot from pressing down too hard on the pedals (all the way to the floor). Over time, however, pedal stops can wear off and will need to be replaced. Check your pedal to see if this piece is no longer present. If it’s gone, just order one from the El Dorado Mazda parts department and install it yourself (or ask our techs to install it for you).

There’s Something Wrong Electrically

Electrical problems should be left to the professionals. If you suspect a wiring issue with your lights, bring your vehicle into our McKinney, Texas, dealership for repairs.
