Our fabulous Light Up Hair is a wild accessory day or night! Even with the LED lights off, get noticed during the day as the springy mesh noodles bounce while you walk. Turn on the LEDs at night for an instant party. Worn to Mardi Gras parades, Halloween parties, 4th of July, or really ANYtime you need a smile on your face, Blue Light Up Hair is a funky good time. To activate your Light Up Hair, slide the switch on top of the black plastic headpiece. 3 AG13 batteries are included and replaceable.
