How do you use 12-volt semi trailers with M931A2 semi tractor?

Dear denizens, how do you use 12v _semi_ trailers, with M931A2 _semi_ tractors that are 24v based?

I need to run the lights only. Trailers are all airbrake based regular semi trailers.

I am sure that there is some robust solution.

OR, you can make your own converter pigtail, and swap out the bulbs with 24-volt ones.

Yes, you can get a M915 pigtail and make your own.

I made a custom interconnect cable and switched all the lighting out to LED's that are good for 12-24 volt.

There is a converter you can buy its pricey but there out there; We make trailers that are 12/24v. Off hand I don't remember the name but I know it has the 7 way built in and its big lol.
