sounds good. Its a good idea to leave your high beams regular halogen. MOST cars have halogen as high beams. One reason is because the intial lighting of HID draws relativly high amperage. Highbeams are usually turned on for a few seconds and off because of oncoming traffic. There would be too much strain on the system having the HID on and off like that. Also its because the yellow light from halogen works better in rain, snow and fog situations.
I am still looking around and trying to wrap my head around all the advice. I would like to hear your suggestions. I am leaning towards at 55W 6000K for my low beams and leaving the high beams and fogs alone at this time, until I see how this works out. I have a Lincoln MKX which has the autoleveling headlights, so I'm not worried about that.
