What do I do if my tail light is out?
If only one of the tail lights appears to be out, the mechanic should check to see if the unlit bulb is burned out. Over time, bulbs will eventually fail and need to be replaced. The mechanic will check the filament in the unlit bulb to see if it is broken. If so, he or she will replace the bad bulb with a new one.
Why is my tail light not working properly?
Common causes for this condition is a loose fitting bulb inside the socket. To test for this condition expose the tail light bulb in question. Next, switch the tail lights on and move the bulb around slightly in the socket. If the bulb flickers tighten the socket or replace the bulb/socket to regain proper operation.
How do you repair a bad tail light wire?
Cut the wire off, leaving enough wire still connected to the socket to splice onto the new 16 gauge wire using another butt connector. Tape the connections very securely. This will help prevent corrosion which will reduce the voltage to the light. Turn the parking lights back on the test the repair.
Can a bad ground wire cause brake lights to not work?
A bad brake light ground connection will result in the brake lights not working, or power crossfeeding through the tail-light circuit, preventing both tail and brake lights froms working at the same time. Repairing the connection is a project that is well within the range of the do-it-yourselfer.
Why are the brake lights and tail lights the same?
Brake lights typically use a dual filament bulb, and it’s possible for just one of those filaments to break. When that happens, you’ll get function out of one side of the bulb, like the brake light, but not the taillight. Furthermore, many manufactures use separate bulbs for the taillights and the brake lights.

How does a tail light control relay work?
Step 11 – A tail light control relay is used to help shoulder the electrical draw many bulbs can cause on a single circuit, this task is carried out by the BCM (body control module). The headlight/running light switch is used as the trigger circuit which sends a signal to activate the relay.
When to take a tail light bulb to the mechanic?
If the bulb is fine, your car may have a deeper electrical problem. If the fuse, taillight wires, and bulb are all in good shape, it’s time to take the car to the mechanic. When you remove a bulb for replacement, you should inspect the socket for burnt contacts and the tail lamp for burnt contacts or melted socket boards.
