What would cause brake lights not to work?

If one or more of your brake lights isn’t working properly, it could mean one of three things: The brake light system fuse is blown, the brake light bulbs are burned out or the brake light wiring switch is broken. All of these issues are easy to troubleshoot.

Does one fuse control both brake lights?

Since the problem is only on one side, you can rule out the fuse and other parts of the circuit that are shared by both bulbs.
