The SIGMA NUGGET FLASH is designed for high traffic roads where safety is top priority. It uses a 1/2 watt high-power LED and our new FRESNEL lens to provide more than 220˚ of lateral visibility. Since it is meant to be used every day, day or night, it is powered by a USB rechargeable lithium ion battery.
This powerful light provides excellent visibility up to 400 meters. Its small size fits perfectly on all bikes, and the belt clip allows you to use it hiking, walking, running, and more.
