I’ve been using the Bull Frog tail light($28) by Knog for a couple months already. Like all of the Knog lighting products, the LED/battery case is encapsulated and affixed to a bike by means of a flexible silicon body. Most readers have seen the diminutive Frog lights, now available in a variety of body colours. I like them, but the Frog’s single LED and CR2032 batteries don’t make for long-lasting brilliance. What I wanted was a commuter tail light.
I present the Bull Frog.
