I ordered mine from Ebay and I believe that's where Swhat got his. He said his don't flicker or give any error messages like yours do. I have hunch that if mine do the flicker and error message it can be remedied with the resistor packs from Umnitza that you can purchase with their lights. Since I don't have my car yet there is no way for me to prove this theory.
If one of you want to try it and let us know that would be awesome.
