If I can make something work right, I'll just bust the glass off the huge bag of expired #47s I've got and solder the LEDs into that to make for easy installation. After a dozen or so, I'd guess the process would go pretty quick and you'd have enough to outfit a game in a half-hour or so. Probably have to make two or three different configurations to replace globes in different types of places, but if it will save burned out globe frustration, that's worth a lot to me.
What about the drop-down resistor?
