All you have to do is change the bulbs to 12 volts and supply the trailer with a 12 volt power source. If you leave the original 24 volt bulb in the trailer they will only glow at 1/2 of their rated wattage.
Use a voltage devider or a transformer.
Change the trailer light bulbs to 24 volts and supply a 24 volt source to power them, in that order.
If your cart has 4, 12 volt batteries in series to make up the 48 volts, just connect the 12 volt lights across one of the batteries.
Parallel.
Yes. Many 12 volt bulbs get very dangerously hot, for instance the 12 volt bulbs that are commonly used in vehicle headlights and in small 12 volt 50 watt overhead ceiling lights in homes.
With some difficulty. Easiest way would be with three lights connected in series, shining at the same time.

change all the light bulbs to 12v
If your cart has 4, 12 volt batteries in series to make up the 48 volts, just connect the 12 volt lights across one of the batteries.
Use a voltage devider or a transformer.
It can be done with 90% efficiency.
With an appropriately rated DC to DC converter.

If that 1940 Chrysler is in original condition, it would have a 6 volt system. Originally, it was a 6-volt. However, many people convert them to 12-volt systems for convenience purposes.
One can purchase a 12 volt light from a variety of stores. Some of the stores that sell 12 volt lights include Amazon, The Solar Store, eBay, and Bulbtown.
With some difficulty. Easiest way would be with three lights connected in series, shining at the same time.
If it is a 12 volt panel it will light a 12 volt bulb. Most likely it is not a 12 volt panel, it is some other voltage, so you then need equipment like an inverter to convert the energy to 12-volt energy.
