most modern cars have a bulb that share the duty.. the bulb has two filaments, one acts as the marker light, and the other works as a turn signal when activated, or as the brake light when the turn signal is not activated
How do you replace brake lights
It depends on the vehicle but in general you would have one fuse for the signals and one fuse for the brake lights.
Brake lights
You probably need to replace your brake light switch. It's near the top of the brake assembly, beyond a trim panel. The fact that all three brake lights don't work rules out problems in the multifunction switch (the cause of similar problems affecting only the two rear lights.)
Fuse 7 controls the brake lights. It should be a red 10amp fuse.
Blown fuse
Brake lights and turn signals are on a separate circuit from the tail lights. Tail lights are on the same circuit with the dashboard lights. If the dashboard lights aren't working either, check the fuse. If they ARE working, check the headlight switch.
Could be the brake light switch or fuse.
i have tail lights but do not have brake lights nor do i have turn signals. i have replaced brake switch and all bulbs
It is not necessarily the fuse. It could be the switch on the brake that is not closing the circuit.
Bad brake switch. Typically located at the top of the brake pedal.
change the fuse if not replace flasher
