Hey any idea what would cause passenger side license plate light not work even though it has power? Tried 2 different new bulbs and neither would work...... even tried spilicing in the drivers side wire to see if that would work but nothing....... these are 1 wire lights........I did do a continuity check from end of wire to the center contact.... no break there..... Any ideas?

 

Corroded socket = no ground

 

Yes, the socket isnt tight in the bumber right now...... found out thats how it gets the grounding done...... Would a wire to the body of the light to the frame work for that....... or just replace the socket itself......

 

Yup, it's all in the ground...

I would replace the socket, but it still has to contact the frame or it won't be grounded. You could use a wire, but if that's what you want to do, get a new socket with two wires, and run one to power and the other to ground.
