Led low beam warning light
Has anyone else had trouble with the warning light after installing leds? Have ordered resistors with h11 adapters maybe that will fix problem. Warning light doesn't come on with daytime running lights just when headlights are turned on.

I had the same issue after ordering CEM "compatible" LED headlights. The flickering associated with "non-compliant" LEDs was gone but that warning message replaced it. Since it's my wife's car I had to go back to standard halogen. No solution yet for me either.
