Be the merriest person at the holiday party or disco with our fun and festive sound-producing jingle bell necklace that lights up! For an extra festive touch, you can connect multiple LED Multi-Color Disco Ball Necklaces together around the tree or table. Each shiny ornament features either a red or blue LED that cycles through 7 different light functions—from morphing to fast flashing to steady on—activated with a simple push of a button. Three of the multi-color balls even include jingle bells for added holiday cheer. Powered by 3 AG13 batteries (included, installed, and replaceable), this necklace is the perfect accessory for lighting up your celebrations!
