I have Morimoto Mini H1 6.0 HID retros in my headlights. One of them was damaged by someone while it was parked. I was going to order new light assemblies and do retros again. I was considering the Mini H1 7.0 or using the D2S. Has anyone retrofit the D2s in an 04-08 Grand Prix housing? How did you like them? Any specific challenges?
