google clearance lights and you'll find almost no end to the options...
I ended up ordering these...except from someone on ebay if I remember correctly, and replaced all of mine

I liked the idea that they were supposed to be sealed. After some time though, I did find water condensed on the inside of them....ugh.... so far they are still working though. I was having some roof work done, and had them do what I was planning to do.... no screws, just stuck down. They used 3M 5200 I believe. I wish they wouldn't have used something quite that permanent though.
My originals from the factory were a horrible design, that had a miserably insufficient foam gasket complete with a nice "cup" designed base to funnel any water that didn't get in through the screw on top.
