With USB rechargeable convenience, multiple lighting modes and excellent side visibility, it’s an ideal choice for commuters, recreational cyclists and road bike riders who want dependable visibility without adding bulk to their bike.

Whether you’re cycling to work before sunrise, heading home after dark or simply want to be more noticeable in traffic, the Knog Plug Rear Bike Light makes everyday cycling safer and more convenient. Its lightweight design mounts quickly to most seat posts, while the long battery life means less time charging and more time spent cycling.

Compact Design with Excellent Visibility

Despite its small size, the Knog Plug Rear Bike Light delivers bright rear illumination and enhanced side visibility thanks to its domed lens design. This helps motorists and other path users spot you from multiple angles, making it a practical safety upgrade for urban cycling and road cycling alike.

Long Runtime for Daily Cycling

With up to 100+ hours of runtime in Eco Flash mode, this rear bike light is well suited to regular commuters and cyclists who don’t want to constantly recharge their lights. Multiple lighting modes allow you to balance visibility and battery life depending on your cycling conditions.

USB Rechargeable Convenience

Forget disposable batteries. The integrated rechargeable battery can be topped up via micro USB, making it a simple and cost-effective choice for everyday cycling. A built-in low battery indicator also helps prevent unexpected flat batteries when you need visibility most.

Fits a Wide Range of Bikes

The included silicone mounting bands make installation quick and tool-free on both standard and aero seat posts. Whether you’re riding a road bike, commuter bike, hybrid bike or fitness bike, the Plug Rear Light is designed to fit securely and stay in place during regular use.
