Our clear flashing, multi-color tube necklace is one of the first and most popular LED items ever made. It came onto the scene several years ago and changed the light up novelty business forever. And after all these years, it still is an eye-opener! We have bought and tested every necklace of this type from every Chinese factory and U.S. importer and have found the BEST and COOLEST looking one available! And we are very, very picky. This particular model measures 26 inches long and features a transparent tube with red, blue, green, pink, and orange LEDs. FIVE DIFFERENT COLORS! (most necklaces of this type have the same old three- Red, Green, and Blue. Ours has those too, PLUS the hard to find PINK and AMBER colors! FIVE different colors makes this necklace a colorful treat for the eyes! A RAINBOW of color around your neck! But those colors don't just sit there looking pretty. They flash and chase in 4 different patterns: circular (the LEDs appear to be moving in a circle), flashing, left-to-right (the LEDs appear to be moving back and forth), and sequential (all first 3 modes repeated). The on/off button is also used to change the mode. These necklaces are a HOT item and a must-have for any party-lover! Batteries are included and installed. Simply remove the small battery protector tab (this tab prevents the necklace from accidentally turning on during shipment) press the power button and be prepared to LIGHT UP THE ROOM! Or the dance floor, the concert hall, the party, the festival, the walk-a-thon, the club, or any other event or occasion where you want to be noticed! And with our dazzling clear flashing multi-color LED tube necklace...YOU WILL! Order yours today! Get an extra for a friend!
