Propper LED Reflective Safety Band provides increased visibility for use in low-light situations where safety is high priority. Easily wraps around wrists, ankles or slide between straps of MOLLE for visibility where you need it. A bright fabric core is enhanced with retroreflective fabric added to the perimeter to reflect light back to oncoming cars. The three-function LED gives 100+ hours of bright glow, flash or strobe to transmit light in all directions.
