Bryton Gardia R300L Rear Radar Light With ANT+ connectivity, brake detection, and seamless integration with compatible bike computers, the Bryton Gardia R300L Radar delivers comprehensive protection and peace of mind for every journey. Advanced Radar Detection: Your Eyes in the Back of Your Head The Gardia R300L's powerful radar system acts as your personal rear-view sentinel, scanning for approaching vehicles up to 190 metres behind you, far beyond what you could ever see with a glance over your shoulder. This isn't just passive detection; the device intelligently analyses the relative speed of approaching traffic and assigns threat levels accordingly. When a vehicle is closing in quickly, the Gardia R300L automatically switches to a more aggressive flashing pattern, actively warning drivers that there's a cyclist ahead. Compatible bike computers provide both visual and audio alerts, ensuring you're always aware of what's happening behind you without taking your focus off the road ahead. Intelligent Brake Detection: Clear Communication with Following Traffic The Gardia R300L's built-in G-sensor automatically detects braking and activates a dedicated brake-light mode. This familiar visual cue instantly communicates your intentions to drivers behind you, dramatically reducing the risk of rear-end collisions during emergency stops or when approaching junctions. Seamless ANT+ Integration: Complete Control at Your Fingertips The Gardia R300L's ANT+ Light Network connectivity transforms your cycling setup into an integrated safety system. Connect the rear radar to compatible headlights and bike computers to control all your lighting from a single device, switching modes, turning lights on and off, and adjusting brightness without fumbling for separate buttons. The system even utilises your bike computer's built-in light sensor to automatically adjust the tail light's intensity based on ambient conditions, ensuring optimal visibility whether you're riding at dawn, dusk, or in broad daylight. Universal Compatibility and Easy Installation The Gardia R300L features a thoughtfully designed universal mounting system that accommodates 27.2mm, 30.9mm, and 31.6mm seatposts, as well as D-shaped and aero configurations. Whatever the bike, installation is straightforward and secure, getting you protected and on the road quickly.
