Magicshine Seemee 400 ANT+ Tail Light

The Magicshine Seemee 400 ANT+ elevates rear-light safety with a powerful 400-lumen burst and a full 360° OptiTracing halo for maximum visibility. Its Optillumin lens ensures strong rear and side illumination, giving riders a standout presence in low-light conditions. Built for road cyclists and urban riders who demand superior safety, the Seemee 400 sets a new benchmark in smart taillight performance.

Instant Reactive Safety: Equipped with an upgraded motion sensor, the Seemee 400 delivers an immediate 400-lumen brake flash—brighter and faster than the Seemee 300. This rapid response alerts traffic earlier and more clearly, reducing braking-related risks. The intelligent system ensures accurate activation even during subtle deceleration, keeping you protected at all times.

Advanced Group & Device Integration: PelotonSync Flash technology allows multiple compatible Magicshine taillights to sync automatically, creating uniform flash patterns during group rides. FTR LightSync pairs seamlessly with the MJ-6558 remote for single-touch front-rear control. Full ANT+ compatibility enables direct connectivity with Garmin, Wahoo and Hammerhead devices for effortless cockpit-level operation.

Designed for Long-Distance Reliability: Delivering up to 107 hours of runtime, the Seemee 400 is built for endurance. USB-C fast charging, lockout mode and a rugged IPX6 waterproof rating make it dependable in all conditions. The quarter-turn mounting system ensures quick, stable installation on seatposts or saddle rails, adapting easily to varied bike setups.

The Seemee 400 isn’t just brighter—it’s a complete upgrade in visibility, intelligence and integration. Designed for riders who expect more from their safety gear, it elevates every ride with confidence and control.
