Will the s4 b6 headlights fit an a4 b6 1.8t?

 

I wouldn't gamble on it. I was looking at headlights on ECS Tuning's website, and it depends on VIN.

Are the old headlights and the new headlights both halogen or both bi-xenon?

 

should be plug and play. Same housing just bi xenon. Might have to up the fuse for the automatic headlight adjustment.

 

Sweet, all I have are the stock ones, but the s4 ones are sweet looking. Are the stock ones halogen or bi-xenon?

 

stock ones are either halogen or xenon. I think s4's were the only bi-xenon package. But other then that its the same housing same setup. Same fourtabs at the back. Should just plug right up. My question is have u consider joeymodding your headlights. Or even just throwin and plug and play hid kit in your halogen capsuls. Its beats paying 500 for headlights.

 

No how much would that cost? I found the s4 lights for a couple hundred on ebay

 

are u sure they are authentic? They might be knock offs. u want to post a link? If you were to say just buy a hid kit it would be about 50 dollars total. If u want to match up the fogs 100.

Those arent stock s4 lights. those are aftermarket. I have heard the cuttoff on most of those lenes are very poor to say the least. If i were you i would just throw a hid kit in your car and call it a day. But if u want the led's then go for it. But dont expect very good lightoutput from those.

 

One of my light sets is messed up it keeps saying the lights are burnt out but when I check them they are fine, I'm thinking it has a short in it
