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.
Ideal for commuters, road riders and anyone wanting a compact visibility light that can also serve as a wearable or emergency backup.
