The Safety Zone pins is really cool...I have never seen another one. The electric part is very simple...just a flashlight bulb under the Green light. When you drop in the "Traffic Light" hole it will light up. Hitting that hole also gives you a free ball....the same ball basically goes back to the shooter ball area. At the same time the ball runs over a lever under the playfield that raises the bars in those 2 angled lanes above the traffic light. This allows the ball to go from 100,200,300 to 1000, 2000, and 3000...look closely and you can see where those bars normally hold the ball at 100. I guess this game was ahead of it's time. Here is a flyer showing $32.50 price tag....using a inflation calculator that is around $550 today.
