condensation in headlight

is this bad to have.. i can see condensation that's inside my left headlight..

I wouldnt worry about it, my left headlight has a hole in it where a rock hit, me and my dad siliconed it pretty well, but water still seeps through.

try to open them heating them up in the oven, clean them & reseal them with special headlight glue, and as Melt said, clear silicone is good for holes. Otherwise, it's junkyard time :)
