Light And Motion Urban 500 Headlight. The Light Motion Urban 500 headlight is all you need for a compact, self contained headlight. Able to handle the demands of the daily commute and powerful enough with a brilliant 500 lumens of light on the brightest setting to satisfy the needs of night time singletrack aficionados. Gram for gram, lumen for lumen, the Urban 500 is the lightest, brightest, and most compact light in its class. Amber side lights ensure there's a full 180 degree visibility, the four light modes enable you to have run times from 1.5 to 12 hours, and you'll enjoy the convenience of re charging via an included micro USB cable. Incredibly light at 121 grams plus fully waterproof to withstand the elements, the Urban 500 is truly a stellar performer once daylight transitions into night.
