Road and gravel riders on busy roads who want early warning of traffic from behind on their bike computer.
The Magene L508 combines a rear-view radar with a tail light. It picks up vehicles approaching from behind at up to 140 m, across a 40° detection angle, and sends alerts over ANT+ to compatible bike computers and to supported Garmin watches, so you know a car is coming before you hear it.
The light has seven modes, including a radar-only mode for daytime rides, plus smart brake sensing and a 220° viewing angle. Battery life runs from 4 to 19 hours depending on mode, and it charges by USB-C.
It's IPX7 rated, mounts to your seat post with the included bracket and straps, and sleeps and wakes automatically.

Great for
Maybe not for
Radar alerts need a bike computer that supports ANT+ radar, or a supported Garmin watch (Magene lists models including the 245, 645, 735, 745, 935, 945, D2 and Fenix 5 and 6 series). Mounts to the seat post with the included bracket, pad and rubber straps.
Aim it right
Mount the L508 upright and pointing straight back, clear of saddle bags and mudguards, or the radar can't see past them. Pair it with your head unit before the ride, and use radar-only mode in daylight to stretch battery life on long days.
