i bought some infiniti fx35 bi-xenon projectors off ebay because i want to use the projectors, not the crappy h4 housings that i have right now. here's a link to the set that i got.
1. how does the projector and HID system work exactly? does the system use a standard bulb and the projector uses it's shutter to dim the light down for the low beam? or does it use some kind of dual bulb setup like the aftermarket h4 bi-xenon bulbs?
2. are bi-xenon ballasts the same as single beam ballasts? if i buy a d2s bulb with harness to be able to hook up to an aftermarket ballast, can i buy any single beam ballast?
3. is the difference between the aftermarket bi-xenon and single beam kits just the bulb? from what i've seen, most kits have some sort of bulb that moves for the high/low beam.
thanks for helping a newbie out
