The biggest difference between the halogen and HID bulb's output is the location of the filament, so the HID's sit in the housing at a different position. I'm sure the reflectors have some minor differences too, mostly to prevent glare.
Just curious, what kind of bulbs came with the car? Does it just have regular halogens in the high beam?
