This awesome light has a bright 7 color ribbon effect and when moved creates a bright continuous LED trail of 7 colors. While most multi-color microlights create a fast-flashing "dotted" effect, it is far rarer to find ones that can create the coveted non-stop ribbon streak effect with an LED that continuously stays on and changes colors. These lights are great for gloving, dance light shows, keychain lights and led rave lights. Turns on both via a squeeze-on and a steady-on slide switch. Uses replaceable CR2016 batteries (included). Features a keychain attachment.
