Garmin's new Varia bicycle headlight is a high-tech responsible headlight that adjusts the length of its beam depending on the speed of the rider. When you're riding faster, you need to be looking further ahead as you're covering ground quicker. The Varia headlight automatically focuses its beam farther up the road when you're in full flow, while broadening to give a wider and less intense illumination as you slow down.
The system works by analyzing changes in riders' GPS coordinates, and determines their speed while focusing or broadening the beam accordingly. Additionally, when the rider brakes, the Varia system boosts the intensity of the tail light, effectively converting it into a brake light. This system means greater safety and convenience for cyclists.
