This is an extremely common problem on this game, I am sure more games have these lights not working than working. From what I understand the lights can short from ball hits causing the chip to blow up. Hmmmm, Not that I think about it, I think the problem had to do with the very thin insulation on the wires inside the blue tubes. I forget for sure...

Tony at http://www.pinballwizzard.com was remaking this board and a new set of Chase Lights for it. I haven't talked to him in a while to see where he is at, but I know he was working on it.

He is the guy who made the lighted wires for the engine in Corvette and his ball trough repair piece is Great!!
