Prepare For What's Coming / Smart Light Change
Auto Light Change
When connected to compatible Bryton bike computers, the GARDIA R300L will utilize the computer’s built-in light sensor to adjust its light mode based on current light conditions. If sufficient light is detected, the tail light will be switched to day flash to conserve battery or when riding in darker conditions, the tail light will automatically switch to night flash.
Brake Detection
Utilizing a built-in G-sensor, the Bryton GARDIA radar tail light can detect when you are braking and notify vehicles behind you with a brake light, lowering the possibility of collisions when slowing down or emergency braking.
ANT+ Light Network
Utilizing built-in ANT+ integration, the GARDIA R300L rearview radar and tail light is able to connect with compatible headlights and bike computers to form a network, enabling both headlights and tail lights to be controlled right from bike computers - including switch on/off and adjusting light mode functions.
