I was playing around with the idea of putting angel eyes on my car when I came across a ready to install Crossfire specific kit. It is made by Oracle, and they seem to be a fairly reputable company. I don't know if anyone else has posted anything about these pre-made kits, and if so, I apologize for the repost. I just thought $199 was a pretty good deal for those of us who are less technically inclined.
