3C Stutter Strobe LED bulbs are like 3 color bulbs but instead of strobing one of each color, it strobes each of the colors twice! BWG Stutter looks like BB, WW, GG! 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.
