Reply to "Z stuff Pennsylvania signal led"

LED's or light emitting diodes come in a variety of sizes: 5mm, 3mm, etc. I'm not sure what size you need for this signal. These are DC devices that require a current limiting resistor. The value for the resistor depends upon the voltage range of the LED. Warm white is closer to lunar white than regular white that have a blue tint. Or you may want to use yellow.
