I've been thinking of changing out the halogens for some xenon headlamps. Does anyone have experience with those conversion kits? I am somewhat concerned about light spread, since it is my understanding that aftermarket xenon lamps sometimes have an irregular throw pattern due to not being explicitly designed for a given reflector. Also, I came across a kit for $80 bucks, which seems pretty darn cheap. Is that the norm these days, or is it junk? If anybody has experience to share, I'd appreciate it.
