Bought a HID H4 conversion kit from Ebay on recommendation from Rob@SCC (he has a H7 on his Golf Mk4)......

Fitted it yesterday and fook me what an easy job.....lol

Before.... (althought on sidelights and not main)



After....




Balast pack....

There's NO additional wiring need, the whole lot just plugs into the std 3 pin plug...
