ASM,
G&K changed the headlights because the origional European lights are not DOT approved. I wonder if your adjustment might need attention as the HID lights G&K installed are very bright. I have the European lights on one of my smarts and to me the G&K lights are brighter. Also the adjusters in the Euro lights are an internal part of the light and cannot be adopted to the HID lights.
Cheers, Dan
