Mine was all cracked and a couple dropped off. I used foam (like the kind in small engine air filters and high end electronic parts boxes). Just cut a small straight piece about 1/2 inch long and about 1/4 inch square (on its end) and stuff it into the holes. That'll keep the bugs and most of the splashed water out. Catch this moisture as close to when you saw it so it doesn't damage the inside of the lens (it can ruin them even if you use the forum suggestion to flush them out with that chemical I can't remember the name of). When they fog up I take a hair dryer and blow it through the assembly (remove both rubber covers at the bulbs and blow into one, also, a low setting doesn't heat it up too hot and the very dry heat produced gets most the moisture out. Cover them rubber covers immediately back (you know, where the bulbs go) and you should be OK for a while. Works for me!
