pop,

My circuit has 3 switches, each of which control one color. The yellow
switch, for example, turns on the yellow bulbs. Same for red and green. Not
sure what you mean by saying: "Your schematic turns them all on at once".

Smarty, do you understand the basic rules of baseball? After a batter
gets three strikes, he's out. If he gets four "balls," he walks to
first. This device is a counter to keep track of how many balls and
strikes the batter has. Each of the individual lights needs to be
controlled independently.
