Cobber Reflex Rear Bike Light
Lumens are a measure of the total amount of visible light from a light source. The higher the lumen rating the “brighter” the light will appear.
Cobber Reflex Rear is engineered to adapt to the ride. Using intelligent Reflex modes, it adjusts to your bike’s speed and angle, maximising visibility when it matters most. Smart, sharp and unapologetically bright.

Amazing how good quality this light is and the brightness and aesthetically beautiful.
Absolutely love it. Bright, individual, customisable. What’s not to like!
… best rear light in the world!
Since the Blinder bike lights (esp rear) came out 10+ years ago, I have been a big fan of the Knog products, and the latest Cobber Reflex is no exception. I really like the extra illumination area, easy to install, accessible lighting modes, usb-c charging - time will tell on battery life and durability - but ok for now.
Been using the Cobbler Reflex taillight and am very pleased. Very bright and great settings!
