7C ribbons are like 3C ribbons but all the colors are connected like a ribbon and do not have any breaks between the colors. It pairs off two colors and mixes them to create the other 4 colors. Great for orbits and glove sets if paired with strobes too! Easily change up the look of your lights by purchasing new colored led bulbs. You can purchase the LED bulbs by themselves or have us install it into a rave light. If you would like us to install it into a housing with brand new batteries please select it from the options.
