The Lezyne Radar Drive LED Rear Light is a premium rear bike light engineered to improve rider safety and visibility with cutting-edge radar-based vehicle detection and a bright LED output. Its specially calibrated radar system identifies vehicles approaching from behind at distances up to 150 meters. The light functions autonomously as a taillight, activating a distinct flash pattern whenever a vehicle is detected.

The Radar Drive pairs seamlessly with the Lezyne React Drive front light to create a truly innovative safety system. Operating independently of any phone app or bike computer, it provides built-in audio and visual alerts through the React Drive’s integrated features. For riders who prefer connected functionality, it can also link to compatible GPS computers or the Lezyne Radar Ally smartphone app, delivering real-time vehicle detection alerts.

Equipped with seven output modes, including a powerful 300-lumen Daytime Flash, the Radar Drive ensures visibility in any riding environment. Its co-moulded construction is compact, stylish, and built to withstand the elements with an IPX7 waterproof rating.

Additional rider-focused features include a USB-C charging port, up to 20 hours of runtime, and a versatile strap-mount system designed to fit round, aero, and D-shaped seatposts with ease. Combining intelligent radar detection with robust lighting performance, the Radar Drive redefines modern cycling safety.
