im planing to do a E46 HID retrofit. I was thinking of doing a TSX But it seems its a lot more work then E46. My question is, they seem to have two different projectors. Single Xenon and Bi-Xenon. Does anyone know whats the difference in between them, also which one might be easy to fit in the Headlight housing, i know that on the TSX The back portion of the headlight needs to be cut, is this the same with E46 kit. Any info or tips would help, and when i do this ill do a nice writeup with Pics. Thanks for reading
