Take your racing to a new level. Tracer Racers utilize Light Trail Technology as they blaze streaks of light on Skullduggery patented Glow-in-the-Dark track. Each Tracer Racer beams down purple light rays from its undercarriage onto track specially engineered to emit glow remnants long after the racer has passed. These racing sets are perfect for both beginning and advanced race fans as variable speed remote control cars and adjustable track heights allow racers to control course difficulty.
