The Moon Sirius Pro 350 Lumen Rear Light redefines cycling safety with its cutting-edge smart features. Emitting a brilliant 350 lumens of red light, this rear light ensures uncompromised visibility, especially in low-light and nighttime conditions. What sets it apart are its intelligent modes, which adapt to your surroundings seamlessly.

Equipped with advanced sensors, the light automatically adjusts its intensity based on ambient lighting, conserving power when it's not needed and maximizing visibility when it is. Additionally, the smart motion sensor detects your movement, switching to a power-conserving standby mode if parked and automatically off after 40 seconds, as well as automatically turning to a brighter steady Lumen when braking.

With various lighting modes, including steady and attention-grabbing flash patterns, you have the flexibility to choose the ideal setting for your ride. Built to endure any weather condition, the Sirius Pro is a rugged companion for every adventure. Its tool-free mounting system ensures quick and effortless attachment to your bike, and the long-lasting battery keeps you illuminated throughout your journey.
