I did one retrofit involving TL projectors into a the headlights of an accord. Although it came out pretty good, the time to do it sucked. I really don't want to do it again, as the baking to remove the plastic casing over the headlight sucked and then I had to reseal it 3-4 times to get the condensation out.
I really just want a sharp cutoff line and from what I've seen, the TSX, TL, S2000 & ZKW lens' get that affect, but the Q45 Gatlings look sweet!
