Knog Plus - 20 Lumen - Rear Light

Small, lightweight and incredibly versatile, the Knog Plus Rear Light proves that great things really do come in compact packages. Designed to be just as useful on your bike as it is off it, this clever rear light can mount to your seatpost or seat stay — or be removed from its mount and clipped onto your clothing, helmet or backpack.

With a powerful 20-lumen output and visibility of up to 450 metres, the Plus Rear Light helps ensure you’re seen in low light and traffic-heavy conditions. It’s a favourite among commuters, road cyclists and anyone who wants a reliable backup or secondary rear light.

Charging is refreshingly simple thanks to Knog’s integrated USB-A connector, meaning no cables to lose and no extra chargers needed. Just plug it straight into a USB port and you’re good to go.

Despite its small size, the Plus Rear Light is built for real-world riding. It’s IP66 waterproof, ultra-durable, and weighs just 17 grams, making it easy to forget it’s even there — until you need it. With up to 40 hours of runtime, it’s ready for daily commutes, long rides, or keeping in your bag as a just-in-case safety light.

Whether you use it as your main rear light or a secondary visibility boost, the Knog Plus Rear Light is a simple, smart solution for staying seen.
