The rave glasses are cool and eye-catching, making you the center of attention at parties. Ideal for parties, performances, rave concerts, and festivals. High-quality EL wire delivers exceptional visual effects and extended glow time at night. Simple to operate with a single-button design. Press the button on the battery pack to switch the glasses between four modes: steady glow, blinking, FLASHING, and off. Ergonomically designed with stylish shiny black frames. Standard adult size and comfortable for extended wear. Visibility is excellent, and the lights do not impair vision. The glasses operate with a battery pack connected by a wire (NOT CORDLESS). The independent battery pack requires two 1.5V AA batteries, providing enough power for a longer continuous lighting duration (at least two hours, depending on the battery used). The pack and glasses connect via a 35" wire, allowing you to conveniently conceal the pack in your pocket, clothing, or clip it to your belt.
