I have a pair of PIAA 1100X's mounted under the mirrors. You can order a kit that comes with the lights, wire harness and switch.
I just installed a pair of Hyperlite turn signals to the license plate bracket AND a pair of Hyperlite NON FLASHING
brake lites mounted on the bottom side of the brake light lens. Next, I want to mount a set of Hyperlite turn signals underneath the PIAA's.
Right before I ordered the hyperlites, I spoke to a local police officer about the FLASHING versions. He told me he wouldn't pull me over for them, but he said it's a possiblity that I could get pulled in another district, state, etc.
Sometime this weekend, I'll take a picture of the azz end of the bike and post it, so you can see how I mounted mine.
