I believe you're thinking of a "cricket", a child's toy, one of the prizes you might get in a box of Cracker Jacks. These were actually only used by airborne troops, paratroopers, and only during the Normandy D-Day invasion, called Operation Overlord. The paratroopers began landing in the middle of the night, before the main force of the invasion landed from the sea at dawn. The crickets were given to the paratrooper so they could tell friend from for in the night - one click was supposed to be answered by two clicks. This was all famously depicted in the excellent movie about the invasion, "The Longest Day". Most of the time the very last thing a soldier on the battlefield wants to do is signal his position. That's a very good way to get killed.

Every time they go where they are not supposed to you scold them an then whenever you take them out to go, at the door that leads you out create a signal like a jingle of a bell so whenever they go in the wrong spot, make the noise of the signal so they know ''Oh that isn't supposed to be there''.

His possession of it was supposed to emphasize and signal that the Scots were to be subservient to the English.
Does the turn signal also blink? If so, you have two wires touching. What happens when you put the vehicle in reverse and the backup light is supposed to come on? If the turn signal lights up and the backup light doesn't, you have the bulbs in the wrong socket.
