Hi there,
Been looking at installing a pair of RHD bi-xenons on my leon. I know for the sake of legality that technically you will need self levelling and washers but unless they are specced on the car from new they are a right royal pain to install. I went a different route with a mk4 golf I had. I bought the housings bulbs and ballasts from ebay. Took time though. Then I got 10 pin sockets from a pair of old scrapper headlights. Removed the 12pins from the xenons and replaced with 10pins. Wired up the levelling motors to the same pins as on normal halogen lights. I then had xenons with MANUAL levelling from the rheostat next to the headlight switch. My outlook on the Leon setup would be as follows: Get RHD headlamps, non AFS ones. Get the 10pin sockets from old set of lamps (any vw golf mk4 lamp would do) and do the dirty job, its easy really. All you would need then was one wire from each lamp (original pin 11) and lead these into the drivers side (no need to remove battery) and connect into the relevant positions for the CECM (A5 and D6 IIRC). Now you have control of the bi-xenon shutter as well. Of course access to VAG-COM would be needed to enable the bit. Once I have part numbers for the proper lamps, i'll be getting a quote from SEREMOTORS. Can get ballasts and bulbs from ebay. Of course there is always the possibility of a complete set of lamps from the scrappy. Will keep you informed of developments...
