Tom,
I swapped out my 120mm halogens and put in 90mm HID Xenon's. Below is a photo album showing the new lamps in my bus. Eventually I'd like to bring the lamps out so they protrude thru the bumper, frog eye style. To finish it off I need a black nacelle. In the Mojave at night I can see 10 miles down the road. The lamps are fantastic.

And, here's where I bought them. I see that they have come down in price a bit (thanks to the crashing euro):
