The design of the website lets you put together the exact kit you need, and lists compatabilities right then and there for you, eliminating the dreaded hunt for parts with 100 tabs open that you're used to. The quality of everything I received was excellent, with wonderfully thought-out packaging. Everything came in one box, making it trivial to move things between my workstation and my garage.
I ordered parts for a full HID projector retrofit with some LED accents, and I've had no issues with the new parts. I've been running the new system for about 4 months now and I love it!
Already convinced a buddy with his own project car to use The Retrofit Source for his lighting needs, once he gets to that stage.
