Be safe on yourcommute with the Kryptonite Avenue F-70/R-35 Headlight. Offering five different modes, the Avenue F-70 helps you stay safe in daylight by alerting drivers of your whereabouts with its bright DayTime Pulse, and at night you'll be able to spot potholes from a distance with its High Steady mode. Then, the R-35 provides similar options but with less lumens to meet the type of light on your ride. Side illumination ports allow you to be seen by cars at intersections, and a built in battery indicator helps you keep track of how much time you've got before you need to plug in for a charge. It's easy to recharge with any USB port, and can last from 10 to 20 hours once fully charged.
