Hello, what isn't he difference between a factory hid headlight and a non hid headlight? I know the first thing is the bulbs, but does the measurements on the physical headlights change? This question is in relation to an 08 club man a.. Thanks.

 

The factory fit halogen and xenon headlamp assemblies are the same size and fitment. The wiring, coding, levelling sensors etc. are very different though, not plug and play.

 

Yea, two different headlight, with basically the same shape, except for the headlight washers on the factory xenon's.
