The Knog Road R70 Tail Light uses 4 LEDs shining at up to 70 lumens providing rider visibility up to 1000 meters out. Its convenient design uses interchangeable rubber straps to mount onto a variety of round and aero seatposts without the need for tools or permanent mounting-fixtures. Side illumination grabs the attention of cross-traffic and an integrated low-battery indicator signals the need for recharging which is easily done using the built-in weatherproof USB plug to re-up the Road R70’s lithium polymer battery.
