Just finished retrofitting some Hella 90mm projector lights into my stock housings. Still not done with getting the beam pattern as best as it can be. Also included pics of the HID in the stock housings. I didn't realise that our stock reflectors were pretty damm good, so for those of you who just wanna go with HID in stock housings, you will be quite pleased at the results.
