Magicshine Seemee 400 USB-C Red LED Rear Light

SEEMEE 400 is a powerful, feature-packed rear light, perfect for road cycling, city riding, and everyday commutes. It has two light sources: a main light and an OptiTracing light. The main light uses two high-power LEDs with a maximum brightness of 400 lumens for high visibility in traffic, while OptiTracing projects a 360° red glow onto the road, making you visible from every direction. The 1600 mAh battery provides up to 107 hours of runtime and recharges via USB-C. The aluminum alloy body and IPX6-rated waterproofing ensure resistance to rain and splashes.

For installation, you can easily attach the SEEMEE 400 to your saddle or seatpost in seconds using the quarter-turn mount. An integrated motion sensor detects braking and temporarily increases the light intensity to 400 lm as a stop signal. ANT+ connectivity lets you control the light from your cycling computer (Bryton, Garmin, Wahoo, Hammerhead), while the FTR LightSync function lets you synchronize it with the front light. It also includes PelotonSync Flash mode to synchronize its flashing with other compatible lights on the bikes of other members of your group.
