Abstract: The present invention enables observers to rapidly determine whether a seat belt is properly fastened. When the seat belt buckle is latched a circuit is completed which activates an array of lights incorporated with the seat belt fabric. When illuminated, the lights provide to an observer positive visual confirmation the belt is latched. The disclosed invention promotes safety by permitting law enforcement officers, aircraft cabin attendants, amusement park ride operators and the like to verify at a glance, regardless of ambient lighting conditions, whether seat belts are being used as required.
