ELumaBoard by King RAT Motorsports is an exciting new product developed for the endurance racer. The ElumaBoard uses the latest electroluminescent technology to create a backlit number board that is as flexible and wafer thin as regular vinyl number boards. When electricity is applied, the ElumaBoard lights up brightly - allowing for easy identification of your car by the team, workers, officials and spectators. The ELumaBoard is a must have for any endurance racer racing in darkness.
