Im currently putting them into my 99 beetle that i got a set brand new from germany.
its not plug and play, early style cars come with 3 pin connectors and the oem hids have 10 pin connectors. You have to really know whats going on with wiring these things. They also have e-code light, and motors installed for leveling that also should be wired with a rheostat
gt2437 has them in his 2000 bug and good old car has them in his but his are wired differently, using non-oem parts i believe using resistors and what not. (they were originally built by r0nd3L) -sold his bug
As far as i know those are the only 2 in the states
tmtuning sells a kit for 2150 (plus add another 100 for shipping charges)and i believe even that is not plug and play. I can get them a little cheaper then that from my contact if anyone is really interested.
I sent my wiring harnesses to pg performance (not cheap), they modify and repin everything , should have them back in my possesion next tuesday. (Owner of pg performance has them installed in his moms 2000 new beetle as well )
The headlight cups are different, i cut a piece from the back replicating the newer style cups (saved me about 70$)
All in all, this mod is way too expensive, to buy and maintain.
I also heard that ballasts go out a lot on these headlights and thats why VW didnt put them anymore in new beetles not to mension you have to take off the whole front clip to install them and if the ballasts go, gotta get back in there again
While im waiting for my harnesses to come back i test fitted them in the modified cups and so far so good. I will have more updates next week
