Projectors exposed to the elements

I've got a street legal dirt bike with a rather weak electrical system. The Baja Designs 55/60W halogen headlight on it just isn't cutting it for light output so I've been looking at options for upgrades. I've been thinking a single 35W HID in a bi-xenon projector would be better than what I have now and still not draw more power than the stator can produce. Specifically I've been looking at the nilight projectors on Amazon.

Problem is to make a projector fit I'll most likely have to mount it directly to the bike rather than behind a traditional headlight lens. Do these style projectors tend to be sealed on their own or do they really need to be enclosed in a sealed housing?
