Could the brake lights be remaining on instead of tail lights? If so you may need a brake light switch adjustment or replacement.
They are two separate circuits. Check the bulbs and fuses first.
it could be a plunger relay switch or pressure switch as some people call them. It will be mounted on the brake pedal arm. but i would check the bulbs first because if it is a dual filament bulb it could have gone out on one filament and not another. if your tail lights work and the blinkers work while the tail lights are on then most likely it is the switch on the pedal
The part of the car that turns on the brake lights when you apply pressure to the brake pedal is called the brake switch. Releasing pressure from the pedal causes the brake switch to break its electrical contact, turning off the lights.
That would depend on the total watt rating of all the bulbs in the tail lights.
Check your brake light switch at hte brake pedal.
Most likely a fuse.
Those tail lights could be the brake lights you are seeing and that would be a faulty brake light switch or the brake light switch is out of adjustment.
There's a switch that the brake pedal engages when pressed that makes the brake lights go on. this switch may be stuck.Or the peddle staying on switch
If the headlights are on and brake lights work but not the tail lights, it is possible there is a short in the electrical wires. Another cause for this could be that the tail light bulbs are burned out. Most vehicles have more than one bulb inside the tail lights to control different lights at the same time.
Look for a fuse labeled TAIL LIGHTS. There are 2 separate circuits, one for brake turn and flasher and the other is for tail lights.
check the fuses
Blown fuse, both lights are burnt out, There is a wiring or ground issue.
Next step would be to check the fuses
Tail lights and brake lights fuse.
bad connection at the bulb, short in the wire or a bare wire. hope it helps. duboff
