If you are talking about the tail lights, they are on a seperate circuit than the brake lights/turn signals. The brake light is actually the turn signal for the side that you indicate to turn. It just may be a fuse or a relay for the tail lights. If not, check the bulbs. Unlikely, however possible that they both burned out at the same time.

I'm having brake light problems on my 1996 k 1500 pickup. My all my bulbs are working , but when I turn on running lights it causes my brake lights to go out and makes my signal lights to flash faste


this sounds like an earth problem , but with the faster flashing turnlights it could be the flasher relay , have you had any work done on the vehicle recently that may have dislodged something ?

93 toyota corolla brake lights stay on when running lights are turn on but when running lights are turn off brake lights work correctly


Short in the electrical system. Work around by pulling fuses specific to brake lights (Exterior) to narrow down the problem. Check relays also.

95' Buick regal, 3rd brake light works, tail lights work, turn signals work, stoplight switch seems to work ie 3rd brake light working, fuse is ok, changed bulbs, but no rear brake lights.


If the third brake light works and the regular ones don't, it is most likely a bad turn signal (multifunction) switch. The switch is able to kill the brakes lights to run the turn signals, and in rare circumstances does this. I've seen it several times. It could also be wiring, especially near the turn signal switch, but it is usually the switch.

Tail lights and brake lights not working - not fuse - what can it be?


Brake light switch, located on upper brake pedal should be checked, that is most likely your brake light issue, but U say tail lights aren't working, but running lights do, tail lights and running lights I would consider to be the same, so can u clarify that for me? Let me know how the u do w/ brake light switch, and if u have issue w/ tail lights?
