7/24/17 – Convert the Annunciator Lights

I finished converting the first row of annunciator lights. Due to the ‘Christmas tree’ lights burning out, switching to 6.3 v bulbs and sockets. I’m keeping the trigger and light wires together to they can use any of the relay blocks on the new relay board. Only 24 more to go!


It’s taking a while for the conversion: check out each bulb / socket, add the +5 power wire, then add the return wire for the relay board.
