Yeah, it's almost like a deal breaker for me.

I had HID in my integra but the optics weren't up for it, and the beam pattern was spread all over the place, with fuzzy edges.

What I am trying to buy is the OEM headlight housing that comes as an HID option on the 03+ Celicas. I am not sure what you mean by retrofiting them as they already come with HID optics.
