Here is a dome light assy. removed from a 42 Dodge car. Light is nice, very nice chrome, and glass lens. Has the bulb holder assy. 6 volt bulb untested. Wire lead cut but has a screw on the light lead so you can put a new wire in this. back part was held in place on the roof with 4 screws. Light might be the same as other Mopar cars from the early 40's but you need to research this to see if this is right for your car. Would make a nice part for a Rod.
