We recommend wearing an armband on each arm or leg. This will give you visibility up to 1/2 mile, ( 1/4 mile N.S.E.and West.). When wearing only 1, armband you are visible up to 1/4 mile on that side of your body. You never know which direction a car may come from and wearing 2, armbands doubles your visibility from all directions.
Each LED band contains a battery pack containing replaceable CR-2032 batteries with an approximately 70-80 hours of use, and a control button. Press the button once for constant illumination, press again for flashing mode, press again to turn off.
The LED safety lights provide approximately 100,000 hours of use and can be seen from a distance of 1400 feet, or approximately ¼ mile and are clearly visible from all angles – front – side – back giving drivers ample reaction time.
The LED armbands are adjustable up to four inches and come in three sizes: Small 1"x13", Medium 1"x15", Large 1"x19" and Extra Large 3"x19".
