The Magene L508 rear bike light combines lighting and radar, detecting vehicles approaching from behind at distances of up to 140 m. It connects to compatible bike computers and watches via Bluetooth or ANT+ and can send visual and audible alerts. It features five lighting modes and a sensor that activates a 3-second alert mode when braking is detected.

The horizontal detection angle is 40°, while the light has a 220° viewing angle. Peloton mode reduces brightness for group rides. The Magene Utility app lets you set radar activation for each lighting mode and adjust the flash or pulse interval; the latter is available as an optional paid feature. The light charges via USB Type-C.
