On most cars, the brake light and turn signal are the same element in the bulb with two elements in it. The other one is the tail lights. The brake light will often burn out sooner because it is used more and the on off is harder on the element. If you have the front amber running lights, it is almost certainly the bulbs.
What else can I help you with?
How does activating the turn signal test the brake light bulb on a vehicle?
In many cases, the brake light and the turn signal use the same bulb.
What would cause both the turn signal and brake light fuses to blow on a 2001 Ford Escape?
short circuits in the turn signal and brake light circuits
Which bulb is the turn signal in the rear tail light assembly?
the bulb with two elements in it is the turn signal and brake light bulb
What causes the tail lights not to work on a 1995 Chevy Tahoe when the turn signal and brake lights do work?
either dimmer switch or blown fuse If you are saying that the tail brake lights are working but the third brake light is not....It may be a defective turn signal switch in the steering column.
What causes a Ford LEFT turn signal to flash fast no left turn rear light no rear left brake light?
The turn signal and brake light use the same bulb. When you get a fast flash, it is from a reduced electrical load being placed on the flasher unit due to a burned bulb. Replace the bulb and this should fix your problem.
What causes the brake lights to flash when engaging the left turn signal on a 2002 peterbilt 379 tractor?
Short to power in the brake light circuit. Most likely, the fault is in the switch itself.
2001 Ranger and the Right Rear turn signal is out though the signal light is also the brake light and the brake light works?
Turn Signal Light Doesn't Work, but the Brake Light DoesMost vehicles use a single lamp [bulb] for the tail light, brake light, and turn signal functions.That lamp usually has two filaments: one serves both the tail light and brake light functions while the second filament serves the turn signal function.You description of the issue sounds like the turn signal filament is burned out, while the other filament is not.Another, but less probable cause could be that the conductor [wire] supplying electrical power to the right turn signal filament has either been cut, or corrosion has built up within one of the wiring harness connectors somewhere in that circuit. Corrosion acts to cut off the flow of electricity.
Which fuse do you change for the right side rear brake and turn signal light on a 1984 GM Van?
If only the right rear brake/signal light is effected it is not the fuse. Inspect the right rear brake/signal bulb, socket and wiring.
Where is a brake light switch on a Nissan?
The brake light switch on a Nissan is located just behind the brake pedal. It sends a signal to the brake lights when the pedal is pressed to turn them on.
Brake lights work but when turn signal is on both brake lights go out?
Check and make sure you have the correct bulb. The turn signal/brake light is a dual element bulb and if you have a single element it does not work properly.
How does the wiring run for a back right turn signal on a Plymouth voyager 1992?
the turn signal switch sends current to the turn signal flasher. it then goes to the bulb. The turn signal switch will turn on the turn signal and when the brake is applied it cancels out the brake light as it is a duel element bulb. 1 element is for brake and turn and the other is for parking lights. you can not have a blinker and a constant feed to the same element of the bulb at the same time.
Why does the Third brake light blink when turn signal is in use?
You probably have a turn signal bulb with two filaments one for the turn signal and one for the brake light. If the ground connection is bad on the turn signal circuit then the current would need to find another path to ground. The only other one available is through the brake light filament to the ground on the center brake light. Try removing the taillight assemblies from the vehicle look for what is probably a black wire screwed to the body or a circuit connection and either tighten the screws a bit or clean the connections.
