This is so cool that it was featured on Today show. Be the light of the party. We are sure you will have more fun wearing the light up tie than the person not wearing one. Available in white, blue, lime green, red and pink. They come with an adjustable zipper strap which means one size fits all! Made up with EL wire and powered by a AAA battery pack. Don’t worry, the battery pack is velcroed to the back of the necktie, so it’s perfectly hidden!
