This intelligent headlamp adjusts its output and beam pattern to changing situations. An integrated sensor analyzes and responds to reflected light. When you start reading a map, the beam becomes soft and diffused. On the trail it uses a wide, mid-bright setting so show obstacles to the sides. When you glance ahead, it brightens and narrows to let you pick out details.
