a guy I work with, has a mondeo and he fitted some of these xenon style headlight kits a hundred and odd quid off ebay or something.
Loook just like the real thing, came comlete with power pack and everything!!
So bright in fact, he gets flashed a lot of the time by other drivers, who think he is still on main beam.
Proper xenon lights are supposed to be self leveling, which is controled by micro switches on the front and rear suspension arms, so's not to dazzle people.
Sometimes a good idea to just get a set of 90/130's or similar and wire them through a relay.
