My right headlight keeps going out! I think I've changed the bulb like 3 times in the last month. Everytime I take the old one out it is broken. Also there appears to be some moisture inside the headlight - noticing a pattern that it happens after it rains or go muddin. Is the bulb breaking due to moisture - how do I fix it? Any help is appreciated.

 

Cold water on hot glass = broken bulb. check for any pinholes in the headlight housing or cracks at the bottom.

 

I had a problem with a left headlight going out every 6 months or so. It ended up being a burnt plug on the wiring. I replaced it with a new one, about $10 at Walmart of all places. I haven't had a problem since.

It sounds like you're getting water in the housing though. Like Alan said, check for cracks and seal them up.
