Electronics, Lighting, & Gadgets - Colored Blinkies

Does anyone know of a source for good blinkies that are colors other than red? I watched this video http://www.youtube.com/watch?v=ALLJfyxs8K8 (Japanese fixie trick riding) and one of the guys has a blue blinkie that looks like it would attract a ton of attention. I've searched on line and only found one (and that one seemed pretty junky). I suppose I could always buy a red one with a clear lens and change out the LEDs, but I've already got enough projects in the works right now.

Powerflare makes colored lights. Have not used them, so do not take this as an endorsement.

Here is another source, however they restrict the blue to law enforcement/ fire rescue it appears.

I stumbled across these looking for something else. Personally i'm a traditionalist and believe that a rear facing blinky should be red.
