Okay.. here are the autopia aftermarket H3 fog lights:
Notice there is a reflector in front of the bulb:
H3 bulb sits inside behind the metal shield:
Not too much clearance for an HID bulb due to the HID bulb having a long back.. The shield is needed also because that's how the fog light mounts..
Autozone Fog Lights (no reflector in front of the bulb):
The mounting for this fog light is separate than the H3 bulb, so we cna probably have the H3 HID bulb stick out of there.
