Why does my brake lights only work when headlights are on?
Premium Member. Please be specific about brake lights: those are the lights that come on when you press the brake pedal. If that signal only works when the headlamps are on, you’ll get doubled brightness. The two signals are entirely disconnected from each other, which is why you have a double-filament bulb.

Does turn signal switch control brake lights?
When we use the turn signal switch, it cancels the brake light signal, on the side selected. If it did not, the lights would stay on and not flash. A bad turn-signal switch may interrupt the brake light circuit when it should not. A broken wire to or from the switch may also cause the lower brake-lights not to work.
How much does it cost to fix a brake switch?
The average cost for a brake light switch replacement is between $70 and $94. Labor costs are estimated between $42 and $54 while parts are priced between $28 and $40.
How do you reset a brake pedal?
