Bring the party to the bathroom with the Underwater LED Bathtub Light, which lights up your bath with bright, vibrant disco colors. The waterproof plastic light runs on three AAA batteries (not included) and throws colorful spots of light on the edges of your bathtub and around the room. The light can be used in a standard bathtub, hot tub, or spa to offer an underwater light show. It contains red, green, and blue LED lights that offer four different lighting combinations and are housed in a clear plastic case. The balancing cap that comes included enables you to float the light on the water’s surface.
