Product Description

Lezyne Radar React System – Smart Front and Rear Light Set

The Lezyne Radar React System combines radar-based vehicle detection with
powerful LED lighting to deliver unmatched visibility and awareness on every ride.
It pairs the React Drive front light with the Radar Drive rear light to give
real-time alerts of approaching vehicles up to 150 metres away.

Riders can receive both visual and audio warnings through the Radar Ally app,
compatible GPS bike computers, or directly via the React Drive’s built-in
alert system – no phone connection required once paired.

With up to 1200 lumens up front and 300 lumens at the rear, both lights
offer IPX7 waterproofing, USB-C charging, and premium Lezyne optics
for maximum safety day or night.
