Change the brake bulb. It sounds like one of the filamits is broken in the bulb. Could also be wiring crossed.
There is a sensor under the brake pedal. These sensors sometimes go bad, and cause your brake lights to become useless, though your brakes work perfectly. This has happened to my in my 89 Accord, and was fixed rather easily.
how did u pull the sensor thing off
I should have asked this question: On an E320, what causes the center brake light to constantly be illuminated when the headlight switch is turned to ON. And 've got the . The left side brake bulb was loose. Once I tightened it up, the center light went off.
they are not brake lights they are fog lights and they turn on because it is for the car behind to see you
are you sure it is the brake lights and not the tail lights. if it is the brake lights you most likely have a short some where. go to a auto eletrican It is the brake lights which turn on. Short in the switch or the wiring?
Check the ground wire to the tail lights.
Often this type of behavior is caused by a bad ground for the lighting circuit. Check the ground circuit for the brake lights.
Most likely a fuse or a bad ground.
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.
Fuse, wiring, bulbs
You can only turn off the headlights by applying the emergency brake. When the emergency brake is on, the headlights will not light. Otherwise the best of my expererience is that they are on all the time. If you have remote start, put the emergency brake on before you leave the vehicle and when you remote start it, the headlights will not be on, but the driving lights (if switch is on) will be on as well as the parking lights.
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
Check the fuses and the bulbs.
Check the bulbs - they are double filamented smaller for brake lights and larger for tailights. Check sockets for power and ground
In this order only. Turn engine off. Depress parking brake. Turn engine on. Lights will turn off. To turn lights back on relase parking brake.
