How do i RetroFIt HID projectors into my aftermarket OEM style 1996 Civic Headlites?
I knwo that tha bulb in there now is a H4 - would i have to fit a H4 kit to it or can it be done another way?

what is Brighter:
a) just pluggin a direct Hella h4 HID kit up to my oem housings?
-or-
b) Retrofitting a PROJECTOR HID kit from another car?
