While not as bright as I really would like, the Piaas are alot brighter than what I was exspecting. Overall I'm really satisfied with them. The build quality is on par, and the installation is pretty easy. The fit is snugg so moisture shouldn't be an issue, although the X5 already has plugs to keep the moisture out of the head lamp....
Sorry about the cruddy pics...Once the weather clears up, I'll try to get some decent pics with them side by side of the M3 (cathode type)halos....
