looking into it further, the h1 bulb appears to go into a H4 holder with one of the prongs missing? is this a H7 fitting?

also, the ballasts make a slight buzzing sound, is this normal?
H7 fitting bulbs have two prongs, H4 has three prongs (dual filament bulb so an extra live needed with a shared ground), and H1 has 1 prong on the back as you know from looking at your bulb...
I think most after-market HID kits I've seen made a very slight buzzing sound, perfectly normal although its only noticeable up close.
In other news...hoping to get an FN2 Type R soon, anything specific to look for? They seem cheap to insure for a car of their type, plenty of nice looking ones around on an 08 plate. Deffo has to be a GT pack, I'd like a late 09 one if I can get it under budget just so it has the xenons and other niceties...
