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 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.
