    Replacing Pool Light gaskets - install dry or ?

    My replacement light bulbs have arrived for my old Pentair SAM Amerilite lights. I have new gaskets. One of the light leaked and was half full of pool water. I want to be sure it doesn't leak again.

    I will install the new gasket around the lens dry, but should I put anything between the rubber gasket face and the metal lip of the light fixture (like a thin coating of pool o-ring lube or silicone) to help the gasket seal - or just install dry as the directions state?

    Bump

    Any thoughts on this? Replacement light bulbs have arrived. I'll be finishing this project tonight. Should I install the new gasket dry or use something extra to help the sealing?
    Maybe I'm over thinking this.

    To update my post - I installed both SAM lights dry. With new Pentair gaskets. The lights where just sitting in the pool (not mounted in niche) to test bulbs. I pulled them out about two days later and both had a little water in them.

    So this time I ran a bead of silicone around the housing where the gasket sits (as shown in photo). I hope this works. Putting it together dry with a new gasket didn't work. I tightened the spring clamp according to Pentair's direction.
    Not much else one can do.

    I noticed you were all alone on this thread. How did that replacement work out for you?
