Bought a new gauge cluster for my '74 2000, why reuse the old rubber bulb bases when I've got a 3d printer?

Got to finish them up, going to solder in a diode to protect at least the charge warning light from reverse polarity, and add some dropping resistors to get the voltage down so the LEDs will be happy. Still haven't decided whether to use white or red for the warning lights, definitely white for the gauge lights. After soldering I'll pot everything in with epoxy to seal them up and make them solid. As long as I get the resistor values right to keep the voltage down at the LED then they should last basically forever anyway.
