Xenon’s fitting

[Stu_b7]

Just a quick question about these lights,
What else would I need to get these working on my car as I have halogen lights at the moment and really need to be changed.

Wiring, coding, possible module upgrade, all of which I can do for you, note headlight switch wiring may need adapting & fogs as hjghline module wiring is different to some.
