I've had quite a few people ask me how I modified my headlights so I decided to make an overview video. This is not an detailed how to, but I'll provide a link below to a very detailed forum post that helped me through doing the HID projector retrofit. As for the DRL light strips, how I made them seemed more important than how I wired them.
