Our 2004 U270 coach has running lights above the windshield that are inset into the end cap. There is spacing between these light assemblies and the fiberglass end cap. Does this space need to be caulked? Thanks.
I personally do not like that mounting method as you do not know if they are leaking into headline area or not. Caulking with a good clear one would stop that but I would first take the light fixture off and seal the wire hole. The other place where water gets in is along the screw so make sure that is protected when replacing fixture.

I used clear silicone around the screws and hole in the back when I replaced mine with led markers. I do not feel the thin foam seal that came with the lights adequate. I did not fill the gapped area around the light and end cap. I have had no leakage in 6 months now. David
I used a clear silocone sealant around the lights and the screw holes.
I like using Butyl tape for bedding stuff that moves from heat/rattles and needs to keep water out.

A boat is very similar to our FT's.
@krush Thanks! I never thought about using Butyl in this application but it makes a lot of sense.
see ya

Krush,
I agree good stuff! I used it for sealing around the window frames, under trim molding and and vent covers on a Minnie Winnie I used to have. It's easy to work with like plumber's putty and usually gives a watertight seal when underneath something that's screwed down. Bought mine at an rv supply store.
