No hide-and-seek with the Knog Blinder 4 bike light, you’ll be found from a block away. Size definitely doesn’t matter with this tiny light as it easily pumps out 80 Lumens in the front, and 44 Lumens for the back to give you a run-time of 3 hours, or 50 hours on flashing.

No worries about changing out the batteries, this little light comes with an integrated waterproof USB port and will recharge in about 4-5 hours.
