This awesome light has a bright 7 color strobe effect and when moved creates a bright dotted LED trail of 7 colors. With an internal microchip that flashes through the colors extremely quickly, your eyes see a color-changing dotted line when the microlight is in motion. 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.
