Hi All, Just upgrading my Audi A4 B7 headlights from Halogen to Bi Xenon using this kit.. (See below) Highly recommend RetrofitLab, best service and support you can get! while I have the lights open I am also removing the Orange turn signal cover and spraying the chrome with matt black. Here are some pics with one done and one not for comparison.
