I'm considering trying this since my lights just suck (I've got the ellipsoids, but they're still not too bright, the highs are great though). I'm curious if anyone has done this and if you have any advice, I wary of cutting up my lights. Also, did it make a noticeable improvement on lighting (not just "looks cool", I don't really care about that).
Finally, where'd you buy you're parts and how much did they cost roughly. People say they can be had for 400, although list is more like 550.
