??? Your brakelights are only supposed to come on when using the brakes. Do you mean that your TAIL LIGHTS don't work? Hey Jose==Your TAIL lights may have a fuse blown or something could be wrong with the head light switch. You just have to check it out. GoodluckJoe The tail light bulb has two filaments in it. One for the tail light and one for the brake light. The brake light part is still connected but the one for the tail light is broken. All of this is inside the bulb. Happens all the time. Just need to replace the tail light bulb.
Fog lights are in the front; they are commonly referred to as "brights" because they are the brighter of the two standard headlights. Brake lights are in the rear; they light up when pressure is applied to the brakes or when the car is in park or reverse.
Possible ground issue at the taillights.
they are not brake lights they are fog lights and they turn on because it is for the car behind to see you
Check the fuse for the headlights. It is probably open.
The brake lights should not come one until you step on the brakes. The tail lights should come on when the headlights are on. If they're weak, maybe there's dirt in/on the lenses or maybe the bulb is old and clouded. Change the bulbs and see if that improves things.
how to change the brakes
Sounds like the brake light switch is defective.Sounds like the brake light switch is defective.
The only way you can completely turn off the headlights is to push in the emergency brake slightly, then start the truck and leave the emergency brake on the slightest setting, and the running lights will stay off. Obviously the brakes will be slightly engaged, but you can adjust the emergency brake so the first click doesn't engage the brakes.
In the back should be tail lights which always come on when the headlights or parking lights are on, and stoplights which come on whenever the brakes are pressed. The stoplights should be brighter than the tail lights, but they should be separate.
IT'S PROBABLY JUST A PROBLEM WITH THE PRINTED CIRCUIT BEHIND THE DASH.
Fuse for parking lights probably blown.
Often this type of behavior is caused by a bad ground for the lighting circuit. Check the ground circuit for the brake lights.
They are either the wrong bulbs or one of the filaments is burned out. The bulbs should have two filaments. One is illuminated when the lights are on. The other is brighter when the brakes are used.
ummm... your brake lights should ALWAYS work whether your headlights are on or not, that's how people behind you know you are stopping.
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.
the brake lights are on a separate cuircut,if your brake lights are staying then it will be a fault with the brake light switch. the switch is located under dash,and will be on or very close to brake pedal.
I would check the rear bulbs. I just had this issue and it ended up my brother had used the wrong bulb, and odd enough it caused the brake lights to stay on with headlights. When headlights were not on and you applied the brakes the dash would light and brake lights worked. Strange, HUH? I must admit before this revelation, I replaced headlight switch and brake switch, with no avail.
Most likely a fuse.
The brake lights and the tail lights are separate circuits. Check the brake light fuse, then check the brake light bulbs, then check the brake light switch.
Is it the taillights or the brake lights? If taillights it may be a wiring problem, If brake lights check the switch on the brake pedal
On my 98 sunfire, the tail lights and marker lights only work if you turn on the headlights. If only the daytime lights are on, the Pontiac on the trunk is illuminated but no other lights at the rear until brakes or turn signals are activated. This is common with a lot of vehicles out there. Daytime running lights are not necessarily the same candle power as the headlights. I can tell a big difference in mine.
you have bad contact in ground cable of the brake lights You might also like to check that there has not been a bulb replacement lately that uses a single contact in a double contact socket. This would have the effect of shorting the brake and tail light inputs and thus turn on ALL lights when brakes are applied or the parking lights turned on.
Check the ground wire to the tail lights.
if you recenly replaced bulbs u may have installed them backwards they should be running lights and brake lights if this is the case they maybe installed incorrectly
