Why don't your brake lights come on when you brake?
Check fuses first but its probably the brake light switch under the brake pedal.
Your tail lights are designed to come on with your low beams so that drivers behind you can see you better. It basically assumes that it is dark out. Im assuming you are referring to your tail lights, as tail lights and brake lights are two differing brightness bulbs in the same lens housing. Your tail lights will come on with your headlights, but your brake lights only come on when you depress the brake…
Does the daytime running lights on a 1999 Grand Prix come on when you start the car or when it is put in gear?
THE BRAKE LIGHT SWITCH IS NOT PUTTING OUT BATTERY WHENEVER THE BRAKE PEDAL IS PUSHED DOWN. CHECK TO SEE IF BRAKE LIGHTS COME ON WHEN BRAKE PEDAL IS PUSHED DOWN. IF BRAKE LIGHTS COME ON, THEN YOU SHOULD BE ABLE TO SHIFT IT OUT OF PARK. IF NO BRAKE LIGHTS, THEN IT WON'T SHIFT OUT OF PARK. IF THIS IS THE CASE, THEN REPLACE BRAKE LIGHT SWITCH.
Brake lights dont work on my 98 gmc jimmy Ireplaced bulb and I replaced switch under brake pedal lights still dont work?
Eagle talon 1995 brake lights are not working But the lights work when the light are on why dont the brake lights come on?
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
if it is your running lights that wont come on, your emergency brake could be on, or the sensor may be reading that it is on. this defeats the running lights. you will know this is happening because the emergency brake light will be on. if this is the case, reach under the drivers side door and with the e-brake off, wiggle the e-brake cable back and forth. the running lights should come back on…
Brake lights should NOT be effected by the headlights. Brake light function is completely independent of the headlights. Assuming you are not refering to the tail lights, or marker lights, which are supposed to come when the head lights are turned on. Not having brake lights when the head lights are on is a big safety problem and should be corrected.
First check if bulbs and fuses are good and see if the back lights come on when you turn on the lights. If everything works and the bulbs and fuses are good then its most likely the brake switch on your brake pedal, its usually the only thing wired to the brake pedal. If its not that you might have a short somewhere but usually its either fuses or the brake switch, both are cheap…
Why would a car's running lights and dash lights come on when the brake pedal is pushed and the brake lights come on with the headlights?
have you replaced a brake light bulb? if you have a combined sidelight and brakelight you need a double contact bulb. if someone has fitted a single contact bulb, eg an indicator bulb, the terminal touches both the brake and sidelight terminals crossing them out, bringing sidelights on when brake and brakelights when s/lights switched on. hope this helps
