Thanks for the link. I only really want to upgrade to Angel Eye was thinking of converting to Xenon as well but this seems as though it will cause more trouble as I only have Halogen set up. I think with the Xenon you need to have self levelling suspension so you dont blind other drivers.
So at the moment just needing to know how I would upgrade to LED rings if I purchased plug and play angel light headlight units.
Will have a look on your link and see what I can find,
