Ideal for commuters, road riders and anyone wanting a compact visibility light that can also serve as a wearable or emergency backup.
The Plus is a slim, lightweight rear light designed to help other road users see you in low light and daytime conditions. Its 20-lumen COB LED output is visible from up to 450 m, while five modes let you choose between a steady beam and longer-lasting flash patterns. The official runtimes range from 2 hours in Steady mode to 40 hours in Eco Flash.
Charging is straightforward: remove the light from its magnetic mount and plug the built-in USB-A connector directly into a compatible USB port, with no charging cable to misplace. A red indicator shows charging and low-battery status, and a full charge takes 2 hours.
Mount it to a seat post, seat stay or the supplied removable mount, then take it with you when you lock up. The included straps suit 22–32 mm+ diameters, while the wearable clip lets you attach the light to clothing, a helmet or backpack. The compact design is easy to carry and detach, although an independent test found the mount could wobble on some aero seat posts over rough surfaces.
