Meet the Magicshine SEEMEE 200, a rechargeable rear light built for road and urban cyclists who crave 360° visibility and smart, low-effort safety tech. It’s bright, easy to charge, and a tad smarter than your average taillight—without turning your ride into a sci‑fi gadget.

One-of-a-kind ground-facing area light creates a noticeable halo under you, boosting visibility from behind and to the sides. USB‑C quick charging gets you back on the road in about 1.5 hours, and you can squeeze up to 50 hours of runtime depending on mode. No more fumbling with incompatible cables—this is USB‑C done right.

Key Features & Design

• 200 Lumens Max Output for daytime safety with maximum brightness when you need it most.
• 360° Visibility with a ground-projected area light for comprehensive rear awareness.
• IPX6 Waterproof design keeps working in all weather conditions.
• USB-C Rechargeable with a full charge in about 1.5 hours—no battery drama.

• Daytime Safety Boost Now you can use the maximum 200 lumens during daytime riding, greatly improving visibility in bright conditions.

NOTE: Runtime will be reduced significantly with the brake sensor active. The SEEMEE 200 is designed to keep you visible and safe in any riding scenario, from quick city commutes to long weekend rides.
