Lights on a EMD F3B unit ???

[e-paw]

Well most of the pictures that I had posted here have been lost to the abiss with the last update. But, as was stated earlier the lighting is railroad dependent. At a minimum, a head light at each end is required. Our F-3b was originally owned by the Boston & Maine. The head lights are controlled manually from a switch located inside each of the end doors, other railroads may have a different system. Hope that helps.
