You might already know this but I thought sometimes the simplest things are overlooked...

Are the light bodies metal to metal contact to the frame of the car? Or is there rust or paint between the light bodies and frame?

The frame acts as the ground and there must be some kid of metal to metal. My foglights rusted a bit and stopped working so I removed them and cleaned off the rust, added some dielectric grease between the lights and frame and voila... started working again.

Hope this helps.
