rear brake lights not workin

ive been having trouble with the wiring for my tails. The lights wont turn on, when i turn the headlights on. everything else works fine, is this a commoon occurence, or does anyone have any ideas?

wrong wiring? unless your 100% sure the wirings right, check your fuses

stock tail lights?
have you been working on it? a wire oculd have been cut or something. especially if it was under your bed somewhere, those are pretty exposed.

aftermarket lights, stock wiring, fuses are good. ill have to go check it all over again, i hate jacking up bagged trucks!

Brake light switch behind the brake pedal...

but isent that for the brake lights, i'm talking about the running lights when the headlights turn on

wait, wait. so is it your tail lights or "running lights" that arent working?

...also moved to exterior

oh sorry man ur post said brake lights not workin...
