$50 OE xenon headlight on ebay
 

Not mine so no interest here. Right side only. Probably works. But for $50 it might be worth a shot. I should have put this in the tech forum I guess, but here it is. http://cgi.ebay.com/ebaymotors/1998-E320-Mercedes-Xenon-light-and-ballast_W0QQitemZ270265327174QQcmdZViewItem?hash=item270265327174

I went with this guy when I got a kit for my motorcycle. He'll make custom kits, etc. You will have to re-do his wiring, but I got good hardware.

For that price, it's probably be made in china, steer clear if so...ever see how many rear tail-lights are on ebay, all from the east? I had to wade thru hundreds, thousands, of ads in order to replace my cracked one with OEM, via ebay....And i did not thow out the old one, small crack that lets water in, drivers side, 92 300td...anyone want it for free, you pay UPS, write back with ZIP for cost

It appears to be an OEM lamp assembly that was removed from a car.

I'll take it if you still have it. 23487
Thanks
