Moon Cerberus Rear Bike Light

Meet the award-winning rear bike light from Moon Sport. With three COB (chip-on-board) LEDs and an impressive output of up to 150 lumens, this super-bright light provides 270 degrees of visibility – keeping you seen from all angles. And with a choice of five steady and flashing modes, there’s a light setting for every situation – from heavy traffic to dark country lanes. If you’re a regular late-night rider or urban commuter, this powerful light is a must-have piece of kit. 

For wetter rides, the Cerberus has a water resistance of IPX7, built to withstand even the worst of the British weather. And when the journey’s over, this compact light takes just two hours to recharge, with a USB-C charging cable included in the box. Plus, to make the battery last even longer, there’s a handy lock system to stop it switching on in your bag.

USB Rechargeable: Perfect for rapid and easy charging on-the-go, a water-resistant USB charging port means you can boost your battery in the car, at the café or anywhere with the facility to plug in the USB-C cable found in the box. The Cerberus can be fully re-charged in just two hours, offering outstanding battery life on all modes. Not sure how much of your battery you have left? The battery and charging percentage indictors help ensure you leave home or work with plenty of charge.

Mounting: Three different sized O-Rings offer a mounting solution for a huge array of seatposts, from 20-52mm in diameter. A rubber pad is included to protect your seatpost from any mud or grit trying to interfere. The Cerberus is not just designed for a round seatpost, either. This is thanks to an innovative hinge system, making the light compatible with all seatpost shapes!

Variable Lumens System: Find the perfect brightness for your ride with Moon’s Variable Lumens System. Available in all five of the Cerberus’ modes, you can choose an output of between 10 and 350 lumens.  A mode memory system means your chosen mode and lumens are already set for the next time you ride, whilst the lock system avoids accidental light activation in your kit bag. Excellent side visibility and an in-built reflector optimises safety wherever you choose to ride.
