Garmin Varia RTL515
Bike radar tail light that warns of cars approaching from behind
From current evidence, the Garmin Varia RCT715 is a compelling upgrade for cyclists who want integrated radar, taillight, and camera safety. It reliably detects vehicles up to 140m away, simplifies setup with Garmin ecosystem compatibility, and records 1080p footage. However, the camera struggles in low light and wet conditions, and the microphone picks up mostly road noise while battery life tops at 4 hours.
