Sorry but I can't resist saying it every time I see threads about those "HID kits".
Putting HID kit in a halogen housing is a BAD IDEA (projector or not). If you look at the cars that have HID as an option, you can easily tell that the projectors for the HID and halogen are quite different even on the same car model. There's a reason for it; otherwise, the manufacturer could have used the exact same projectors/housing to cut down cost.
For HID in halogen housing, you will have glare, blurry cutoff and the visibility is short. So people usually end up aiming them higher, which in turn blinding the on-coming traffic. You get a false feeling that it's brighter, it is because the glare lights up your peripheral vision to make you feel that it is brighter.
To make it work the way it is supposed to, it needs a shroud to confine the light. The shroud can get rid of the glare and gives a sharp bluish cut-off (or purple-ish like the Audi/BMW).
I had a company called Custom Lightz (see sig) to do a retrofit for me in my Integra with JDM long headlights. They used TSX projectors and shroud, and painted my housing gunmetal. The result is stunning:
They have done hundreds of retrofits, and besides TSX projectors, they have also used projectors from E46, A4, A8, S2000, TL, E55, Porsche (Hella), MDX, Evo, etc etc and mate them with other shrouds (or custom shroud). Angel eyes, CCFL, LED, anything you can think of they can retrofit it.
I will have them work on my 4Runner next. Thinking about TL bixenon with custom shroud, and keep the housing chrome. It should look and function great.
IMHO, it's not just the appearance that matters, it's a safety issue too (for you and the ones who share the road with you). I'm not trying to flame anyone who is happy with their HID kit, just some of my opinions that I think worth sharing.
