Lezyne launched the Radar Pro 300, a new rear bicycle light and radar system that detects approaching vehicles. The device aims to improve cyclist visibility and awareness during rides.
Why it matters
Radar-equipped lights provide cyclists with an active warning system for vehicles approaching from behind. By detecting traffic early, riders can better monitor their surroundings on busy roads.
The Radar Pro 300 is a hardware device featuring a 2000 mAh battery that supports 24 hours of operation in radar-only mode. It provides a 150-meter detection range and includes an IPX7 waterproof rating.

The details
The device uses radar technology to identify approaching vehicles and communicates this data to paired head units or smartphones via Bluetooth and ANT+ connectivity.

Health Landscape
The Garmin Varia rear radar series established the standard for radar-integrated cycling safety lights, which the Lezyne Radar Pro 300 now joins as a competitor in the category. This release signals an ongoing trend toward integrating active vehicle-detection technology into everyday cycling gear.
Cyclists using radar systems should verify connectivity with their current head units or smartphones to ensure consistent alert reception. It is also worth confirming that any new mounting hardware remains secure before every ride to maintain effective rear-facing visibility.
The takeaway
Radar taillights provide an extra layer of situational awareness for cyclists by alerting them to approaching traffic. Ensure your device is properly charged and paired before long rides, and always use your eyes to scan the road in addition to relying on digital alerts.
