You wanting the Anzo's with the projector low beam, or just the regular halogen bulb lense model? Most of what I hear about putting HID's in a housing that was originally designed for a halogen bulb has been that the light pattern does not have an upper "cutoff" and the pattern is scattered too much rather than aimed. Blinding most oncoming drivers and not giving you the usable light where you want it, on the road. I was thinking the projectors are supposed to prevent that. Or should I say, they are supposed to be designed for HID's. I have seen a couple sets of the projector headlight replacements on eBay with the HID's included. Been thinking about trying a set. Would love to know if anyone else has. I just went through the debate of doing this on my 05 Deville which has 9006 bulbs, and opted to not do the HID's and went with a special bulb made by Toshiba called a HIR bulb. Their 9012 is supposed to be the same as a regular 9006. I didn't do the HID's (the real ones with the ballasts and all) because of what I heard about them not being designed for the halogen lenses.
