I have them. Solved the visibility issue with Radiantz 2.81" direct base red 1157 48 LED clusters. They are bright, very bright, and from any angle. I set them up to be turn/brake, instead of run/turn/brake. I feel that off to on is more of a change when braking than just dimmer to brighter.
I supplemented the caddy tails (although they need no supplement) with a radiantz 128 LED tail, red SMC LED replacement reflectors above my plate, run/brake red plate strip on the bottom of plate frame, and flexible red strips around the inside of my sissy bar. Both reflector LEDs and backrest LEDs also work as turn/brake. I also added this:

I know, you'll want pics. I really need to take some and share some of the stuff I have done to my bike, but my Works Street Trackers should be arriving soon and I need to mount my new wheels to be finished, and I want my pics to be the finished bike...so I haven't yet taken pics. I know, a work in progress howto would have been nice.
