The CT we have is equipped with LED from factory on low beam and fog light, but high beam has halogen.
Will install LED and if they look to me OK will go with the LED next year and see what they will say. They should have no problems with the LED as the headlamp has the washer and automatic level for the LED as low beam are in the car with LED from factory. I suppose the car will pass and they will not say anything, probably not even notice. I will not put super bright in, just white LED with about same lumen as the halogen. 5500 - 5800 Kelvin is what I find correct, but will probably end up with 6000 as that is what is sold. Yellow light was modern in 1970 -80 in French cars, but today it is not so.
