I've been looking into this (came across this mod when I was overseas) as a solution for running HID's in my STI - I must be getting old as I find the factory halogens woeful. HID conversions to the OEM reflectors just throw light everywhere and have eye straining hotspots in the foreground, not to mention annoying every other person on the road.

The solution is to retrofit proper HID projector lenses to the lamp housings.



This conversion to the OEM housings gives you the proper light distribution required to legally run HID's, they have Hi/lo beams, proper beam cut off and do not glare if adjusted correctly.

Low beam


High beam


Note: Both images above show LHD light patterns - be sure to order RHD projectors if you want to do this mod.

The only change I intend to make to the mod is to use Plasti Dip to tint the factory reflector to stop the internal reflections inside the lamp housing.

These are the projector units I bought:



Once they arrive I'll post up the whole conversion process.
