Running Light sealant

Searched but no luck..I assume Thor is using basic silicone to seal around the running lights? Yes? No?
While I see no leaks Inside it looks like I need more protection. Would you agree?

Good for you being proactive about preventing water intrusion! I donít know what Thor uses, but I use clear urethane caulk on my sidewall seems and fixtures. Itís a little harder to use than silicone because itís pretty sticky but itís a superior product. I inspect my roof and sidewalls 3 or 4 times a year for smooth, well bonded, unbroken sealant around every single window, fixture and seam. I learned my lesson the hard way. It was a very expensive lesson!

I had to seal my porch light as it was filling with water when the cover drain hole got plugged with goop. The water filled the fixture to the wires and the water wicked down the wires to where they loop under the fridge. That water filled the drawer under the fridge with an inch of water and soaked the carpet on the floor in front of the fridge. I removed the porch light, no sealant, no gasket but a 3/4Ē hole the wires pass thru and the light just screwed to the side of the coach. I remounted the light and ran a bead of clear silicone around the top of the light. No more leaks after 2+ yrs.
