Portland Oregon's public transit system (TriMet) sells tiny blue blinking LED lights to their riders. The idea is so the bus driver can spot you at a dark bus stop. The light is only $1, small enough to clip onto your jacket, but the light level is pitiful.
What could I get that would be brighter but still small enough to clip on or carry on a keychain? First thing that comes to mind is a Photon, it meets all the requirements (tiny, blue, bright, blinker), but are there other choices?
