Why does my brake light work sometimes?
If you have a single brake light out and the bulb is good, then the next step is to check the light socket itself. Brake light problems can include a socket whose connections are dirty or corroded, or one whose wiring has become worn to the point where it’s only making an intermittent connection.
What stops brake lights from working?
When your brake lights don’t work, it is usually because of a blown fuse, a worn-out or broken brake light switch, or a burned-out light bulb. One or more lights don’t work (though at least one light works). None of the brake lights work. The brake lights stay on and refuse to go off.
