Is it just one side that does not light up? Have you tried replacing the bulb? The bulbs should be double filament bulbs that are with running lights and brake lights.

Ok, you need to just replace the circuit board that all three bulbs plug into.

Ok, look inside the connector where the bulb goes into. Does it look burned or melted? What is the bulb number you have in there now to replace the old one?
