    I am not sure why my license plate light isn't working. I have almost 12V (~11.5V) running to the light. The housing is very corroded so I was going to clean that up. I did clean up the connection that goes into the light bulb. I was looking to replace the bulb with an LED and realized that I did not have a light working at all.

    Is there a ground I am missing or something? I just see one wire.

    It grounds through the mounting. Probably corroded.

    I will clean up the mounting metal of the actual housing. I assume it is grounding where it attached to the bumper then and I need to clean that part up too? Basically, the nonchromed part of the bumper.

    Where the mounting screw goes through as well.

    I just went thru this. Had to clean it up really good to get proper ground. If I recall correctly bulb to socket and socket to housing and also housing to bumper. And I used dielectric grease also. If you have a multimeter I would test continuity across each component. Good luck.
