The Knog blinder 4V has four extra bright LEDs that produce 44 lumens of light. Its optimized optics focus and directs a smooth beam pattern that makes the blinder visible over 800 meters away. With 5 different light modes, (steady, fast flash, organic flash 1, organic flash 2, and eco flash) and a burn time of up to 3 hours in constant beam and 50 hours in eco- flash, feel certain that you’ll be seen.

Comments about Knog Blinder 4 V Black Pulse Light:
Best USB charge led light out there. Battery life is kinda short but you can always charge it with your laptop or wall socket with an apple adapter. Has different modes depending on riders preference. Once strapped on will stay strapped on. Worth every penny!
