Introducing the Voyager helmet light kit. This is the smallest, lightest, brightest, and baddest helmet light of them all and puts out some serious light. Designed for the extreme night riders of the world, the rechargeable lithium-ion battery powered light will run at full power for over 3 hours. Weighing in at just 2.1 ounces, you won’t even be able to feel this light on your helmet. There are three power settings; low, medium, and high. This lamp is incredibly bright, allowing you to ride faster than ever through the night. The lithium-ion batteries allows the light to stay bright throughout the duration of the battery use. Meaning, the light will not slowly dim like many headlamps. The Voyager comes with 4 battery power level indicator lights, allowing you to always know the range of your remaining battery power. Perfect for mountain biking, dirt biking, snow biking, snowmobiling, skiing, enduro riding & more.
