The new Knog Frog Strobe puts out a stunning 11 lumens of light. That's really bright for such a little thing. And it does it while still looking cool.
Great little rear light (red) for night rides or cloudy days. Easy to keep handy in case you get caught riding in the dark unexpectedly.
Great, simple design. Very secure so long as the tube is large enough to create resistance when stretching. Three different light patterns (solid, continuous strobe and 3 blink strobe). Light weight and low profile...stays out of the way and easy to take on and off. Easy to turn on/off. Very simple design + great execution = quality product.
