I was looking at some HID conversion kits on Ebay as I don't like my standard halogen headlamps. However, I've since found out that it is illegal to retrofit a HID upgrade.
So my question is... is it possible to upgrade my headlamp units to Xenon? If so, is it just a case of purchasing the Xenon version of the E60 headlamp or should I be aware of some electrical differences such as the Ballasts?
Also, on a slightly different note... is it possible to upgrade to adaptive headlights rather than fixed? I presume some sort of coding and extra hardware/looms would be required?
