CYCPLUS L7 Advanced Bike Radar Tail Light with with Precise Brake Sensing, Real-Time Vehicle Detection Up to 160m, IPX6 Waterproof Bicycle Rearview Light for Night Riding

The CYCPLUS L7 Smart Radar Tail Light is designed to enhance rear visibility and riding awareness with advanced radar technology in a compact, lightweight form. Its patented radar system detects approaching vehicles from up to 160 meters behind, helping riders stay informed of traffic conditions during city commutes or open-road rides.

Using built-in FMCW radar technology, the L7 delivers real-time alerts directly to compatible Garmin and Wahoo bike computers. Visual and audible notifications keep riders aware of approaching vehicles without needing to turn around or lose focus on the road ahead.

The tail light features 270° wide-angle illumination with high-brightness LEDs, ensuring visibility from the rear and sides in low-light, urban, and daytime riding conditions. When fast-approaching vehicles are detected, the light automatically switches to rapid flashing to draw immediate attention from drivers.

An intelligent brake-sensing function detects sudden slowing or braking and activates a bright warning signal, clearly indicating rider movement to traffic behind. Multiple preset light modes—including constant, blinking, breathing, and radar-only—can be customized through the CYCPLUS app to suit different riding environments.

Built for long and demanding rides, the L7 offers up to 36 hours of battery life in radar mode, supported by motion-wake and auto-sleep technology for efficient power use. Weighing only 67 g and rated IPX6 waterproof, it’s ready for everyday cycling in varying weather conditions.
