I had toyed with the idea also, but ended up bailing on it since they're illegal in NY. Technically you can't have any colors other than white facing forward(only), red facing backwards(only), and ambers visible from the front,rear, or side. So I guess you could probably use amber LEDs and if ever asked say they're "marker lights".
They have bike checkpoints like that around me and I know a guy with a Goldwing that lights up like a Christmas tree got ticketed for it at one. Ticket was for "distracting lighting" or something. Little ******** stuff like that is what NY's all about now in it's big money-grab, err, "safety", checkpoints.
Like Chris said I kind of thought it would be a bit ricer-ish as well, and quality kits are not cheap. Decided the money could be better spent elsewhere.
