On My 1998 Toyota Camy when the car is on my brakes lights wont go off but if the car its off the brake light work fine why??


These Toyotas had daytime running lights. The headlights and the taillights turn on when you start the car. If you press the brake pedal, the rear lights (and the brake light in the rear window) should come on brighter.

I have never heard of the brake light staying on (The brighter filament in the two-filament bulb). Hope this helps.

When I turn on my headlights my brake lights stay on all the time without applying the break pedal. They work fine when the headlights are not on.


Brake pedal you mean. Electrical short somewhere. Somehow power is flowing from the headlight circuit to the brake light circuit. Pull the fuse for the brake lights to see if they stay off, this may help you to isolate the problem. You have to trace the wiring (and test voltages along the way) with the help of the wiring diagram. It's possible corrosion somewhere is also the problem.

It may sound silly, but check your brake light bulbs to see if they have been installed incorrectly. Brake light bulbs have two filaments, one for tail light, and a brighter one for brake lights. On some cars if the bulb is installed wrong, the brighter filament will stay on for tail lights. The only other thing I can think of is the wrong bulbs have been installed.

My brakes lights stay on when my headlights are on, but the brake lights work fine when my headlights are off. Do you know what may be the problem?


This problem likely is the filaments touching in one of the dual filament bulbs used for the brake lights. Another sign of this would be the dash illumination lights coming on when the headlights are off and the brake pedal is pressed. The solution is to replace the defective bulb.

Tail lights stay on when car is off


Check this 1st.With the car running,turn on the headlights.If the taillight gets brighter,it's the brakelight that is staying on.Turn the headlights off to see if that then makes it less bright.If so.try lifting the brake pedal up.If the taillights go out,it is the brakelight sensor switch that is hooked up to the brake pedal.This is a small pushswitch,located at the top of the brake pedal in the inside of the car.It will have 2 wires connected to it.It either needs adjusting or is faulty.Hope this helps

Right tail light not working when pressing brake w/ lights on.


There should be at least 2 bulbs in the light assembly. One light is the light that is on when you turn on your headlights with out the brake pressed, the other light only lights up while you press on the brake. Make sure you are replacing the correct bulb. You may have been replacing the bulb that stays on. Your lights may be set up to turn off the light that stays on when the headlights are on while pressing the brakes.
