Los Angeles - We all know lines for public restrooms can get pretty long at big events, but now one company wants to change that. They have designed a traffic light system for stalls. It is called the Tooshlight. It lets a person know when stall is in use and when it free. A red or green light illuminates at the top of the stall. Red means it is in use and green means it is available. The system is in use at the Hollywood Bowl in Los Angeles.
