I thought about the tape, but was worried about the thickness. I may get tape and replace the foam pad and do one light and see how it works.

For sure, I will use silicone to fill in the hole behind the light. (They drilled through the fiberglass when the coach was built). Also will try to seal around the wires with silicone.

I am really surprised at how these light are mounted. I would expect the wires to be sealed and that any water behind the light would not be able to get into coach. That is not true at all. There is actually a pretty big hole behind the light and another where the wire is. In other words....if the edge of the light is not sealed, the water has an easy path into the coach.
