This set of 8 boards will replace the old metal bayonet lamp sockets that have become unreliable with easy to change 555 style twist sockets.
The new boards have 555 socket holes so that you can change the lamps easily in the game without unscrewing the panel.
You can use either LED or incandescent type.
The board set comes with instructions, a chart of the lamps, standoffs and hardware.
If you need the twist sockets, they are available separately on this web site.
Installing it involves unsoldering and resoldering each wire one at a time.
