You are bidding on a used PASSENGER SIDE (Right Hand) HEADLIGHT removed from a 2001 Audi A6 Quattro. This is an OEM Item made by Hella of Germany and not some inferior after market piece of crap. This Light is not original but is an updated OEM replacement made in 2006. This Headlight should fit all Audi A6 models built from 2000 through 2003.  But to be absolutely certain please carefully examine the Hi Res Pics which show the Light and make sure  that this Item satisfies your needs This Unit comes with one ordinary Bulb, one Halogen Bulb and  one HIGH INTENSITY XENON BULB AND BALLAST. I even took some Pics with Bulbs lit. Not only does it show that all  Bulbs works but the Pic  is meant to simulate night time driving and to demonstrate the clarity of the Lenses. Also if any major defects were present, they would be clearly evident by back lighting the Lenses in this manner.  The plastic Lens is clear like the day it was new. It has no cracks no chips, and no discoloration. The most you can quibble is some minor surface abrasion typical of  light subjected to 7 years of road dust. The Rubber Seal is still soft and malleable. The Internal Mirror coating is Excellent. All mounting Tabs are intact. It takes 4 Bolts to install but I must admit it is not a particularly easy job and probably is best left to a professional. This Light would cost you 800 dollars new complete like this one at almost one-third the cost. This comes with HID Ballast, and three fully functioning Bulbs and Bulb Holders.
