Color temps other than what the HID bulb naturally produces are done with light filtering. That only reduces the total lumen output compared to a transparent type glass. Standard HID bulbs properly aimed should be more than enough for driving at reasonable speeds. Of course that may require an aim that is not DOT standard.

I am by no means an expert, but I have replaced all of my HID bulbs because my wife does not have great night vision. According to her these may make an enormous difference. Check the link.

I didn't read all the other posts subsequent to this one, so forgive 'if a repeat, but, the lenses seem to have pretty much proven they CAN'T take the heat from the existing 'bulbs, have they not? :shrug (Discoloration, cracking, and whatever else?)

I don't know the extent of the cracking in the US. But the export cars that had the lights on all of the time seem to have a higher rate of cracks developing in the headlight lenses. Some US cars have reported this as well. My guess is extreme heat cycling may be causing the problem, Canadian cars seeming to have more reported issues. Another reason not to drive your car in cold winter night.
Of course if you never turning your lights, on even to test them in the garage, they should last forever!
