hmm I did not know that. I would just splice into the power wire on the low beam and run it to the 12v trigger of the HID harness. They also make HID bulbs with a HID and incandescent bulb on the same bulb base.
Might be something you could look into. An HID kit for that specific type of bulb would come with provisions to be able to keep the incandescent filament functional in the low beam headlight.
