The Knog Plus is a slim, credit-card-sized light that mounts almost anywhere with a silicone strap. It suits riders who want a backup light that lives permanently in a bag or jersey pocket. Despite the size it puts out a clearly visible flash for daytime and night riding, with several modes to choose from. The silicone strap wraps around bars, seatposts, saddle rails, a helmet strap or a bag loop, and there is a magnetic option for clipping to clothing. It charges by folding out an integrated USB plug, so there is no cable to lose. Key features Ultra-slim design that fits anywhere Multiple steady and flashing modes Integrated USB plug, no cable needed Silicone strap mounting Water resistant Available as a front or rear light. The best insurance against a flat main light.
