DC Locomotive Constant Lighting

[jdmilliman]

I have several older locos that I would like to add DC constant light to.  Does anyone have any information as how that is done.  I heard that there was a schematic that used several diodes to have the loco lighting on at all times before the engine would move.

 Any help is appreciated.

Thanks, John  Forsyth,IL
