After doing research for 2 weeks I am still very confused. First, I don't own an S4, I own a B6 a4 that came with halogen lights. I bought a pair of S4 Bixenons to swap over since I wanted HIDs.
Right now, I have a set of housings but no hid kit. I understand that these take D1S bulbs, but can I just buy an aftermarket hid kit for these lights instead of forking up 300 + for them. Can I buy like an h7 hid kit and just install them on or is it required I get a d1s or d2s with adapters for it to work?
The reason I ask is b/c someone said I don't need d1s and I can just get h7's and throw them in.
Thanks,
Nick
