• Get up to 24 hours of battery life in day flash mode and up to 30 hours in radar-only mode
• See visual alerts for small, medium and large vehicles approaching, and see the movement of a vehicle and its threat level — when riding with your compatible Edge cycling computer or the Varia app on your smartphone
• Show other cyclists or motorists that youre slowing or stopping with a brake light that displays a unique flash pattern
• Same-speed tracking means you can continue to stay alert to vehicles that are following behind at the same speed or attempting to pass (tracking may be unavailable at slower speeds or when radar is obstructed)
