A 300 lumen tail light with rear radar. It tracks vehicles from up to 140 m behind, at 5 to 100 km/h, and flashes brighter as they approach. It sends approach alerts to compatible cycling computers like Garmin, Wahoo and Hammerhead, and the Magicshine App gives real-time rearview alerts and turns radar and vibration wake-up on or off. Seven modes, including Group Ride and Only Radar. USB-C charging in about 2.15 hours. IPX6. 113 grams.
Quick answers
- Do I need a bike computer? Not to use it as a tail light, and it flashes brighter as cars approach. Approach alerts come through a compatible computer or the Magicshine App.
- Does it have a brake light? Magicshine does not list one. If you want a brake light, see the SEEMEE 400.
- How long does the battery last? It depends on mode and whether radar is on. Magicshine lists Low at 14.5 hours with radar on and about 32.5 hours with it off, Eco Flash at 24 hours with radar and 100 hours without, and Only Radar mode at about 26 hours.
- Is it waterproof? It is rated IPX6.
Why we carry it: for riders who share the road with traffic from behind and want to know it's coming, especially if a Garmin or Wahoo is already on the bars.
Care guide: charging, cleaning and storage.
