Garmin Varia RTL515 Radar Tail Light - Rearview Safety for Cycling


The Garmin Varia™ RTL515 Radar Tail Light is a must-have safety essential for Colorado cyclists riding on busy roads, shared paths, or near traffic — providing reliable rearview radar detection of approaching vehicles up to 153 yards (140 meters) away, combined with a bright LED tail light visible from up to 1 mile in daylight.

This compact, easy-to-mount unit pairs seamlessly with Garmin Edge cycling computers (including the Edge 550, Edge 850, and Edge 540 Solar), compatible smartphones via the Varia app, select Garmin smartwatches for haptic/voice alerts, or third-party apps like Ride with GPS for overlaid radar data on maps. Visual and audible alerts keep your focus forward while staying aware of cars from behind — perfect for Erie-area commutes, gravel routes, or trails near roads.
