That's just the thing, I'm not sure if the my2004 reflectors for halogen and HID are identical. If they are, then the design must have been such that the beam pattern won't be off.
However, I'm almost sure that if the halogen reflectors off of my2002-2003 imprezas are fitted with aftermarket hid, the beam pattern wouldn't be quite right.
