if there are water spots you probably have a leak/crack somewhere. that'* what caused your light to burn out. a hot glass bulb that gets water on it is a no no........
i'd first try to track down a crack/leak. cuz ur just gonna keep blowing bulbs if water is getting inside the assembly.
also.....i think the stock bulbs are just plain 55watt h3s. but u can always upgrade to silverstar h3s (kinda expensive) or i recently bought pilot hyper white h3s (6.99 at autozone). i love the pilots......better than the silverstar h3s in my opinion!
good luck.....if nothing else u might need to spend the $40 and get a new set of cyberwhite assemblies
