Our 8 bit inspired Blue/Red LED Pixel Gun features built-in LEDs and is 11" long by 6" high. Each push of the on/off trigger button lets you cycle through three light settings: strobe, fast flash, and slow flash. Each Blue/Red LED Pixel Gun comes with 3 AAA batteries included and installed. Great for any 80s, Minecraft®, or classic arcade-inspired parties. Perfect for completing your Halloween costume, too.
