Magicshine SEEMEE 400 Rear Light

The Magicshine SEEMEE 400 is the ultimate flagship in rear-light safety, engineered for cyclists who demand maximum road presence and cutting-edge connectivity. This powerhouse takes the proven dual-LED architecture of the SEEMEE 300 and pushes it to a blistering 400-lumen output, making it visible from up to 3km away even in peak daylight. It features the signature 360-degree "OptiTracing" halo light, which projects a protective red glow onto the road surface to ensure you are seen from every angle. With integrated ANT+ technology, you can control your light directly from your Garmin, Wahoo, or Hammerhead bike computer, creating a truly integrated cockpit experience for the high-performance road cyclist or daily urban commuter.
