Get someone's attention with these silly lighted brim hats. With an adjustable velcro back strap, one size will fit all. These hats are constructed with a push-button battery pack that fits snugly into the seam of the hat for non-exposure. 3 Different light settings are available for each hat. Click one time for a slow blinking light show, click 2 times for a quick blinking light show, and then three times for a simple and steady light beam around the brim of the hat. Each hat is made from black 100% cotton, and are available in red or blue lights.
