Well, I did this mod myself and it was pretty easy. However, when I folded the plastic back the hinge snapped off and when I used the nail I expanded the metal housing for the electrical connection. called Buell and they didn't offer a part number as the connections were to loose causing on and off lighting conditions. I ended up cutting all wires and using electrical connectors leaving black and white together and just placing yellow with orange on both sides. works great more visible for those who dont ride and that dont pay attention on the road. good information:[
