Naturehike Africa's Motion Sensing Waterproof Rechargeable Headlamp is designed to accommodate campers, climbers, trail runners, and adventurers pushing it before dawn and after dusk. When the motion sensing mode has been selected the headlamp activates or deactivates on motion in a close proximity to the headlamp for example a hand being moved across. This allows for easy operation of the headlamp eliminating the need to cycle through different modes to switch the light on or off. The headlamp has a second mode which allows for the cycling through different light modes. This headlamp is also waterproof, so don't sweat it if you find yourself in some wet conditions. The direct USB charge design allows you to charge the light with your computer or USB charger so that you always have light.
