Engineered for the Outliers: Why Choose a Knog Bike Light?
Knog rear bike lights are built for riders who don’t follow the pack. Technical in performance, unkonventional in design, every light in the range is made to solve a specific problem on the bike. From ultra-light wearables like the Plus, to pattern-driven Blinder lights, through to the wide-angle Cobber, high-output R-150, and the intelligent adaptability of the Cobber Reflex, each product is purpose-built for a different kind of ride.
What unites them is visibility that works in the real world. Not just what’s behind you, but what’s coming from the sides too. That’s where side visibility matters. In traffic, at intersections, on multi-lane roads, most risk comes from angles, not directly behind. From the Cobber Reflex’s 330-degree beam arc to side illumination across the range, Knog rear bike lights are designed to make you visible where it actually counts.
This is rider-first design backed by serious light engineering. Advanced LED construction, considered optics, and durable, waterproof builds all come standard. The result is a collection of rear bike lights that don’t just tick boxes, but actively improve how you’re seen on every ride.

Finding the Best Bike Rear Light for You
Choosing the right rear light comes down to how you ride. For road cyclists and commuters, the R-150 delivers powerful output with added side visibility, helping you stand out in busy traffic from multiple angles. If your riding spans commuting and gravel, the Cobber Reflex offers adaptive performance with a 330-degree beam that keeps you visible across changing conditions.
If being seen in traffic is your priority, the Blinder Rear uses distinctive flash patterns to grab attention fast in dense urban environments. For minimal setups or riders who want visibility higher up, the Plus is designed to be worn on a helmet, backpack or pocket, keeping things simple and effective.
