Been digging out some engines I haven't run in awhile. I have three older mth. A berkshire, Mohawk and a yellow belly hudson that I would to install backup lights in the tenders. I have identified the two wires ( yellow and white) that go to the motors from the reversing board that might work for what I want to accomplish but the voltage is too high for a led, almost eight volts dc using a 1033 on the bench. I don't know much about electronics so I was wondering if someone could help figure out what I would need to lower the voltage to make this work. Thanks

Well, the Hudson has a 1.5V reverse lamp output on the board set, you can use that with a 1.5V bulb.  In order to use motor voltage for LED's, you'll want a 470 ohm resistor and a diode for reverse voltage protection connected across the drive motor feed lines.

Thanks John. I'm very inexperienced with electronics, would you be able to provide a sketch of installing the resistor and diode? Sorry to be a pest.
