Early pinball machines from the 1930s, all the way through the 40s and into the 50s, used a method of keeping score that was unique to the era.  "Lighted scoring" was a way for the game to show you your score and to keep track of your current score for the purpose of awarding replays.  I describe how lighted scoring is controlled, and the similarity between it and its successor, the score reel.
