Magicshine SEEMEE 300 Rear Light

The Magicshine SEEMEE 300 is an incredibly powerful, flagship smart rear light designed for maximum protection during high-speed road cycling and long-distance touring. Featuring a dual-LED main light that pushes out a blistering 300 lumens, it ensures you are visible from up to 3km away, even in mid-day sun. True to the premium SEEMEE lineage, it includes the 360-degree "OptiTracing" light—a downward-facing LED that projects a red safety halo on the ground to define your personal space to motorists. Housed in a durable, heat-dissipating aluminum alloy body and powered by a massive 1600mAh battery, the SEEMEE 300 is the ultimate "set-and-forget" safety tool for riders who refuse to compromise on visibility.
