Those are MMX Xenon projectors. The bulbs you are probably seeing on e-bay for "mad cheap" are nothing more than little lightbulbs painted blue to look Xenonish. I have a set myself, they work pretty well. The headlight part is as follows:
Lows: 9006
Highs: 9005
Those are the numbers.
And now to the guy with the projectors. Niiiiice!!

Where exactly in the Sahara desert do you live, though, that requires you to have the projectors, hyperwhite fogs, AND a third set of fogs?
