Are you sure they are HID and not aftermarkets as mentioned in this article? I find that most HIDs seem to shine LESS light up into my eyes as oncoming traffic, because it is so well isolated down onto the road, with less being sent up higher. My old Audi's that had HIDs would adjust the height of the headlights whey you started them, to account for load in the trunk and back seats, which tend to lift the headlights up more. ISTR that there were regulations about the amount of light headlights could put out, and HIDs were more effective largely because they eliminated light going where you didn't need it, and were able to concentrate the light more out and down than up.
