I can think of a dozen reasons off the top of my head why Knog Frogs are the best new thing in bicycle lighting since the dawn of the LED. But the best reason isn't their cost ($12) or the color range (13) or the fact that they come from Australia. It's that they simply won't break or stop working, ever. This weekend alone I witnessed two riding buddies break lights when they dropped from a seatbag or handlebar. Don't let that happen to you ever again.
