The only way I've found to have non-leaking clearance and ID lights is to use seam sealer (Dynatron-550) around the screw holes and wire holes when installing the lights. I don't like it because I wanted to be able to install all my lights early and then paint later and they're difficult to remove once they've been glopped up with seam sealer.
Hopefully somebody else can point you to some light assemblies that are actually waterproof from the get-go. I have failed in the task, myself.
Thatís really interesting. And sad too lol. Especially to hear your experience with ones that have a rubber gasket leaking worse somehow
Iím going to try out proflex around all the screw holes that come into the interior and around the light cover to see if that fixes it. I will post pictures/results when I can. Iíve had good luck with the ProFlexRV Sealant on other applications so far (skylights, a couple of bent rivets, roof deck, etc).
