A friend gave me a few of these awhile ago, thought I’d try them out. They are 9w, and dont let the size fool you they are bright! They can be had on ebay for around $6.00/pair ordering from US.

I chose the mounting position because they point slightly out, slightly down. There are other places on the same plastic piece that would create a different effect.

Wired underneath plastic panel:

Had to cut some of the fender out behind the panel where I mounted them (right next to the taillight, each side). You can also see where the wire comes through, ran the wires right along the taillight wires.

Will add more pictures tonight
