Lezyne | Radar REACT System Pair

Your cycling sixth sense.

The Lezyne Radar REACT System is a fully integrated front-and-rear light setup that does more than illuminate—it actively alerts you to what’s happening behind you. Combining the powerful React Drive front light and Radar Drive rear light, this system uses radar technology to detect approaching vehicles and deliver real-time visual and audio alerts.
