Howdy fellas!  I have a set of headlights from a mid-60's GM loco and I would like to wire 'em up for the "high" beams on my hotrod.  I'm having trouble finding what voltage they're supposed to run at though.  I believe it's somewhere around 87VDC.  Can anyone shed some light (pun intended) on this for me?  Also, are there any online sources to find replacements bulbs?

and these folks may be able to offer guidance
And this will be of interest
I would also suggest contact with the Association of American Railroads for information on standards over the years.

Locos electrical systems are 74 volts. The use a multiswitch and resistors for hi and lows. Hope that helps
