Tracers are very cool, they have 1 or 2 colors that strobe and then a different trail that's always on behind it. Think of an asteroid that has a trailing color behind it. 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.
