Magicshine SEEMEE R300 Radar Rear Light

The Magicshine SEEMEE R300 is a cutting-edge radar rear light that transforms your bicycle into a proactive safety machine. Beyond serving as a powerful 300-lumen taillight, it features high-precision radar technology that detects approaching vehicles from up to 140 meters away. By pairing with your Garmin, Wahoo, or Hammerhead bike computer, it provides real-time visual and audible alerts on your screen, allowing you to focus on the road ahead while maintaining total awareness of the traffic behind you. With a massive 3350mAh battery and a robust aluminum housing, the R300 is the ultimate endurance safety tool for solo road riders, commuters, and high-speed tourers who want the peace of mind typically reserved for motor vehicles.

Key Features

• Vibration Wake-Up: The light automatically enters sleep mode after 5 minutes of inactivity and springs back to life the moment you move your bike.
