The Magene L508 radar tail light combines rear-approach radar with a rechargeable cycling light. Pair it with a compatible display to see approaching vehicles while riding, or use radar display in the Magene Utility app.
Rear-approach awareness
Radar detects approaching vehicles at up to 140 metres, with a 40-degree horizontal detection angle. Visual and audible notifications are delivered through the connected display, not a built-in display on the light. Radar is an awareness aid: it does not replace looking behind, listening or checking traffic before manoeuvring, and cannot guarantee detection of every vehicle.
Seven modes for different rides
Choose solid, flashing, pulse, peloton, quick flash, rotation or radar-only mode. The lower-brightness peloton setting is designed for group riding. Smart brake sensing, automatic sleep/wake and an approaching-vehicle warning flash add practical ride functions. Update firmware in Magene Utility to access supported modes and settings.
Check your display compatibility
Connect to a bike computer or other display that supports the standard ANT+ Radar protocol. Bluetooth connects to Magene Utility. Compatibility varies by device and firmware; having ANT+ or Bluetooth alone does not mean a device supports radar alerts. Phone and bike computer shown in photos are not included.
