I have photos, but can't see a number on them. If yours are impossible to reach, and you need to know urgently, send me an instant message. I have spares in my garage at home and can look this evening.
I don't know if this will work, but I'll try to post an image here
I had problems with these fixtures. The foam gasket material was deformed from heat so they leaked. the dealer made their attempt at fixing it, which I'm pretty sure entailed sending a 6 year old up there with a silicone caulk gun. So anyway, i ended up getting replacement fixtures from Thor under warranty and replacing them all myself. I'm on the hunt though, for better fixtures and I'll swap them out some day. The teardrop lens fits down into a lip that forms sort of a bowl, so that water has no choice but to do battle with the gasket. Just a bad design all around..... I saved the old fixtures and bulbs, so that's why I have easy access to them.
