A visual aid for football spectators includes red and green lights on poles associated with a particular game object, which are selectively energized by remote control to indicate the success or failure to achieve the particular game object. In one embodiment the poles are goal posts and the lamps indicate the success or failure of a touchdown, field goal or conversion attempt. In another embodiment the poles are yardsticks and the lamps signal the achievement or lack of achievement of a first down.
