Lezyne Radar Drive 300 Rear Light

Rear Radar Light That Knows What's Behind You The Lezyne Radar Drive 300 is a high-performance rear bike light built around a custom-tuned radar system that detects vehicles approaching from behind in real time, up to 150 meters away. When traffic closes in, the light automatically triggers its own unique alert flash — no phone or head unit required. Seven output modes, including a 300-lumen daytime flash, and precision-engineered optics deliver 270° of visibility so you're seen from every angle in any light condition. The Radar Drive is designed to work in multiple configurations. It can run as a standalone taillight, pair wirelessly with the Lezyne React Drive front light for a self-contained audio and visual alert system, or connect via Bluetooth and ANT+ to compatible GPS bike computers and the Lezyne Radar Ally app for real-time alerts on your screen. A co-molded IPX7-rated body, USB-C charging, and a strap mount compatible with round, aero, and D-shaped seatposts round out a light built for serious riders. Engineered for Every Ride, Every Road Custom-tuned radar detects rear-approaching vehicles in real time from up to 150 meters away. Automatic vehicle-detection alert flash activates the moment traffic is detected, independent of any paired device. 300-lumen daytime flash and seven total output modes for visibility in all conditions, day and night.
