Converters for 12 Volt and 24 Volt vehicles and trailers

Towing a 24V ex-military trailer with a 12 Volt vehicle can be easy or hard, depending on how many functions you need to operate. The hardest function is the brakes, the easiest function is the running lights, blinkers brake lights and turn signals fall in between.
Likewise, 24V vehicles have a similar problem with 12V trailers.
Furthermore, a full NATO military trailer connector will have provisions for rear fog lights, right and left side running lights, stop lights (brake lights) reversing lights, brake wear sensor, parking brake employed under loss of air pressure, and lift axle. From SEC.
