Knog Plus Rear Light

The Knog Plus Rear Light is an impressively simple light that weighs almost nothing, yet at 20 lumens is bright enough for a useful visibility boost. The magnetic mount, cable-free charging and decent battery life in the flashing modes make it perfect for winter training.

The slim body of the Knog Plus Rear Light is full of COB LEDs, and can be plugged directly into a USB port for charging, meaning no cable is required. Plus it's just 18 grams (including the mount), and the 'face' is only 66mm x 14mm.

The light attaches to its mount via a strong magnet, which loops via elastic band around your seatpost. Attachment is quick and easy, and the magnet means you can even reach back mid-ride and clip the light in.

It takes four hours to fully recharge, and offers five modes. Tester Nick Cox favoured the Pulse mode, which easily outlasts most winter rides with its claimed 8.5hrs. While the longest claimed runtime is Eco Flash at 40hrs – it's still pretty visible, too – while the shortest is Steady at 2hrs. Both the Pulse and Steady match the battery life claims.

Its 20 lumens is enough for a driver to see you. In being simple it’s far less bulky than many brighter, more feature-rich and expensive lights.

Overall, it’s a brilliant rear light with good visibility and great design. Given its tiny size and weight (and affordable price) it's also a great second light or emergency backup.
