The Knog Blinder Square is a compact, high-visibility light designed to be seen rather than to light the way. It suits urban riding and daytime running lights, where being noticed is the whole job. The square lens shape presents a distinctive, recognisable form to drivers, which stands out better than another round point of light in a busy scene. It is small enough to leave on the bike permanently, charges over USB, and offers steady and flashing modes for day and night use. Silicone strap mounting means it fits almost anything, including a helmet strap or bag loop. Key features High-visibility square lens for driver recognition Multiple steady and flashing modes USB rechargeable Silicone strap mount fits bars, seatposts and bags Water resistant Available as a front or rear light. Run it in daytime flash mode as well as at night.
