It's Road Show. The game is linked in the post. All the flashers for Road Show are controlled by the 8-Driver Auxiliary board.
First thing to do is check the orientation of the 26-pin ribbon cable from the CPU board to the 8-Driver Auxiliary board. The red stripe on the ribbon cable indicates pin 1 and should align with the silkscreen for pin 1 on both boards. When installing also check you don't install the ribbon cable off by one row.
