I always seem to have water sloshing around in my clear bumper lights. Should I consider a better o-ring or something at the bulb or maybe just apply a coat of silicone around the seam of the lens-to-back?
TIA!

Sounds like you need to invest in some of that JDM blinker fluid, I hear its a lil thicker and wont leak as easy.

Ok seriously, what I did on the wifes was take a teeniny drill bit and drill about 10 holes in the bottom of each side and the center lense. The only way you see them is if you look extremely hard for them, and we have yet to have a problem with them anymore.

now THERE'S an idea!
Another project for the dremel. hehe.
