first check brake light fuse second check light bulbs,they should be double element third check the brake light switch located on the brake pedal
it would be the brake light switch about 20 dollars at autozone
brake light switch would be most common cause
Check your fuses. Sometimes it is just that simple.
What fuse is for the 2005 Ford mustang Rear Brake lights?
change the fuse if not replace flasher
the turn signal switch is probably bad
No , the rear brake lights do not turn on when you use your parking brake , just the brake light on your dash is supposed to come on
the brake light switch is out of adjustment. Readjust the switch.
Taking your foot off the brake pedal...?
No, the license plate light is wired in with the rear tail lights, not the brake lights.
Bulbs blown, or corroded sockets.
Check bulbs, fuses and brake switch in that order.
