Radar React System

What Our Gearhead® Experts Are Saying:

"The Radar React has completely changed how I ride on busy roads. The radar pings me before I even hear a car, and the bright lights ensure I’m visible from every angle. It’s slick that I can control both lights through my GPS or app—no extra clutter, just safety that works."

The Lezyne Radar React System elevates road safety by combining radar-based vehicle detection with Lezyne’s class-leading LED lighting. The system pairs the Radar Drive rear light and React Drive front light, creating a seamless wireless setup that not only illuminates the way ahead but also warns us of vehicles approaching from behind. Unlike basic lighting kits, this system integrates radar technology to provide real-time alerts, displayed via the Radar Ally smartphone app, compatible GPS head units, or directly through the front light’s onboard indicators and audible signals.

The React Drive front light delivers up to 1200 lumens and runs for as long as 70 hours, making it suitable for both nighttime endurance riding and daytime visibility. The Radar Drive rear pushes up to 300 lumens and holds steady for 20 hours, ensuring visibility even under bright sunlight. Together, the system establishes a fully integrated lighting and safety platform, offering disruptive flash patterns, reliable waterproofing (IPX7), and modern USB-C charging for quick top-offs.

Designed for cyclists who demand both performance and safety, the Radar React System is ideal for commuters, gravel grinders, and road endurance riders alike. It transforms the riding experience by combining visibility and situational awareness, letting us focus on the road ahead while maintaining a constant awareness of what’s coming from behind. This is more than a lighting setup—it’s a comprehensive safety system built for the modern rider.
