Magicshine Light Seemee 150 Rear

The Magicshine SEEMEE 150 Rear Light is a compact, smart safety light designed for urban commuting, road cycling, and everyday visibility. Delivering up to 150 lumens of output, it provides strong rear presence both day and night, helping riders stay clearly visible in traffic-heavy environments.

A key feature is its smart sensor system, which includes brake detection, ambient light sensing, and motion activation. When you slow down, the light automatically increases brightness to alert following traffic, effectively acting like a brake light for your bike.

The SEEMEE 150 also uses a wide-angle 260° beam with COB LED technology, ensuring excellent side visibility as well as rear coverage—an important safety advantage in intersections and urban riding.

Designed for convenience, it includes USB-C (or USB) rechargeable power, a lightweight body of around 26 g, and multiple mounting options including seatpost and saddle rail mounting.

With multiple smart and manual modes plus long runtimes (up to ~44 hours in eco modes), it balances visibility, battery efficiency, and everyday usability.
