Official Happyrun G100 Rear LED Taillight & Reactive Brake Safety Light Assembly

Pro-Grade Rear Visibility for High-Velocity Street Commuting When you are pilot-riding a high-power machine like the Happyrun G100 at night, being clearly seen from behind is just as critical as illuminating the path ahead. The Official G100 Rear LED Taillight delivers intense, wide-angle crimson illumination that pierces through heavy rain, dense city fog, and pitch-black suburban corridors. By projecting a brilliant, high-contrast glow, this tail lamp ensures approaching vehicles can easily track your position from blocks away.

Smart, Reactive Brake-Cutoff Synchronization What elevates this factory module above a standard, passive bicycle light is its hardwired interaction with your e-bike’s internal electronic brain. Featuring a built-in reactive braking sensor array, the taillight instantly transforms into a high-brightness warning beacon the millisecond you pull your brake levers. This instant visual transition communicates your deceleration to traffic immediately, preventing rear-end collisions and giving you complete peace of mind during sudden city stops.

Rugged All-Weather Armor with Plug-and-Play Setup No cutting into factory wires, no custom soldering, and no messy electrical tape required. This official safety asset comes pre-equipped with an authentic, water-sealed multi-pin quick-connect harness plug that snaps directly into your G100’s rear electronics channel. It draws continuous power straight from your e-bike’s high-capacity main lithium battery bank, turning on and off perfectly with your dashboard controls. Wrapped in an impact-resistant, IPX5 waterproof casing, it easily shrugs off heavy tire spray, thick mud, and severe road vibration.
