The Model 1634 LED Yellow Traffic Wand features a bright lumen output with a yellow 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 Yellow Traffic Wands are ideal for daylight or overcast applications and are the perfect choice for air ground crews, directing traffic, or marking a potentially hazardous area.
