The back light in my car won't turn on at night.
There are many lights in the rear of the car; they are easy to test. The bulb is usually the problem. If it is not, then he circuit will need to be inspected. Check the fuse, check the socket, check for power and ground. I recommend having a certified technician, such as one from YourMechanic, come out to your car's location to run a diagnostic inspection of your rear lights, and suggest the best path to repair.
