directional problem
edit: its the driverside directional more often, but the other day both burnt out...
If the socket is really nasty, you might have to replace it. But if you dry it out and clean it up, and put some dielectric grease on it, you will probably be OK.
But the reason it's getting wet is cuz of your cracked lens. There is a seam that runs right down the middle of the lens that always cracks. Take some clear caulk and rub it on that seam, wipe off the excess. That'll fix that....
Good luck!
