You could purchase "real" HIDs with ballast from some cheap, Chinese manufacturer; that will work for a very limited time before you have problems. Then you can't run down to the store and pick up a new bulb or ballast. You'll have to send your old one in for a warranty. In the meantime, you can deal with the PITA of swapping out to your old bulbs that came out. You can also spend all of your time getting hi-beamed by oncoming traffic because your light dispersion is ALL over the place. Up in trees, eyes of oncoming drivers, etc. A "real" HID is designed to be housed in a projector headlamp housing and not a bowl from an incandescent lamp. When you see "real" HIDs at full power, there is a distinct cut-off line when you pull close to a solid object (i.e. a wall). When you just put an HID bulb in an incandescent housing, you lose this cutoff and all of the focused light that you would normally get with a projector housing. If you want a real HID upgrade, check out theretrofitsource.com for some valuable information on the right way to perform a "real" HID upgrade. Otherwise, go buy a set of 55 watt HID bulbs and spend your nights pissing off everyone you share the road with (to include police officers, who will ticket you).
