  1. So good so far

    Posted by Mike on Apr 1st 2016

    I have had these in my Audi s5 for a few days now. Nice clean white light. No flickering and best of all. No error codes.

    They were a pain (for me) to install. After about an hour, I finally succeeded. They look so much better than stock. Goes perfectly with my black 2010 Audi A4. Would highly recommend.

  3. Works perfectly on 2010 Audi A4.

    The lights work like charm on my 2010 Audi A4. I was able to leave it at about 45 degree angle as John at hid concept recommended. It's not too bright but bright enough in clean white color. Best upgrade for the money spent.

  4. Thumbs up!

    I've been using these on my B8 A4 for 5 years now.
    No error message and it still working like charm.
    I bought another for my wife's Q5. It works perfectly as I wanted.
