24v trailer wiring

[maple_leaf_eh]

I am considering a long distance roadtrip towing a civilian cargo trailer with my M151A2. It will be a one-way trip for the trailer, so I do not want to put a great deal of effort into the wiring and lights. I have a set of magnetic trailer lights that could be re-lamped to 24v. I have the SMP vehicle to trailer connector cable with a dozen individual shielded plugs. The lights are already working with a 4-wire system.

What does the collective wisdom suggest? Where can I find 24v lamps for commercial 12v sockets?
