I didn't change any sort of programming. I wasn't aware i needed to. The headlights themselves do not flicker. The flicker is the Halos and only when the headlights are on. Its a weird problem and I'm starting to think it might be an issue with the light.Did you change the light setting in the PCM to LED? You can do that with JScan or Tazer. Wondering if that might help. What about the lights themselves....do they flicker?
Update: The problem has gone away by itself. I'm glad but also concerned it might come back. Oh, well guess I'll see as time goes on. Thanks for the help everyone.
