Correct lights for 1948 JD M

[ThreeEdwardsM]

I’m working on the lights on my 1948 John Deere M. It currently has one light and no wire going to it. I also have a couple exposed/unused terminals that may be old lighting connections.

I’m trying to figure out what lighting would be correct for an early M.

Questions:

• Did early M tractors commonly have one front light, two front lights, or no lights depending on year or options? How about rear lights/fender-mounted lights/work lights?
• What rear light/work light was correct if at all?
• Were the MI/MT/MC lighting setups different?
• What are the correct style light arms and housings and where to source them?
• Good sources for correct reproduction lights?
• Anyone using LED bulbs inside original-style housings on 6V positive ground?
• Any wiring diagram tips for the light switch and front/rear lamp feeds?

I’d like to keep it looking original but functional.

Thanks for any photos or parts info.
