With this rear light you are not only seen better, but can also see better in conjunction with a Garmin Edge bike computer or smartphone. It warns you of vehicles approaching from behind.
The Varia RTL515 from Garmin is a rear light with radar. During the day, drivers of approaching vehicles can see you from a distance of up to 1.6 km. In addition, the Varia lets you know what's happening behind you: it provides visual and audible alerts to warn you of vehicles approaching from behind at a distance of up to 140 meters. The smart and compact radar pairs with your Edge cycling computer or compatible smartphone, as well as certain Garmin wearables or the optional radar display unit. The battery lasts a long time - up to six hours in classic mode and up to 16 hours in flashing light mode. The tail light is small, compact and stylish. It can be easily mounted on the seat post. Due to the vertical design, it does not interfere with your legs when riding and also does not affect the driving experience.
