I've sourced the original porcelain "pony cleat" sockets used in the real 191X, so at least for my 1:1's this should make wiring very simple and add some accuracy that no one will ever see but me.
I'll need to start working on the electronics system next for synchronizing the back and forth flashing of the lights, and also build in some functionality to dim the LEDs on shutoff/startup, likely via capacitors. I'd like these to look like they have incandescent bulbs in them without the drawbacks of using them. I don't want to risk any fires, and since my replicas aren't made of metal and borosilicate, I'd rather not take chances. Plus, LEDs are cooler in both senses of the word, and use less power, right?
If anyone is interested in information about the real globes, at least some of them are made by Kopp Glass: FAA Runway Approach model 3522.
