In my Audi A6 Avant the headlights were dull and blind. In wet road was not much to see though the TÜV had no objections. Original was the workshop me then too expensive. Polishing is not so good works as expected. Therefore, I ordered this. Installation according to instructions on the Internet, already went very fast at 2nd. I had completely new lamps worried because I did not want to screw several times. From the old headlight I have expanded the xenon ballast and the servo motor for automatic headlight range control and incorporated into the new headlights.
Has everything despite 0 degrees, worked out great. I am very happy with the result. Finally, I can at night again read the street signs :-) :-)
