The Model 1634 LED Blue Traffic Wand features a bright lumen output with a blue cone and a black formed handle for ultimate grip and comfort. One body mounted push button controls the On/Strobe/Off lighting functions. Pressing the button once, turns the light on constant-on mode, pressing the button a second time causes the light to strobe, and a third press of the button turns the light off. Power comes from 3 premium AAA batteries (included). The lightweight Nightstick LED Blue Traffic Wands are ideal for daylight or night applications and are the perfect choice for air ground crews, directing traffic, or marking a potentially hazardous area.
