So, my car came with xenons when new, stupid shop replaced them with halogens while i was deployed when someone smashed my headlights in storage.

so do i HAVE to get the EXACT model number xenon headlights, or will any xenon headlights made for my b8 fit without needing programming or what not.

for example, my car didnt have the curve light feature, so if i get a set that has curve light will the plugs or anything be different?

and are all the b8 ballasts and led control units interchangeable or are they specific per model/feature style headlight?

i just want them to function safely (high and low beams, turn signals, corner lights, and DRL/LED)

thanks so much in advance!
