The primary components of a transport trailer's electrical system include the battery, wiring, fuses, and light assemblies. The battery serves as the power source, providing the necessary electrical energy to operate various systems on the trailer. Wiring connects the components, ensuring that electricity flows effectively throughout the system. Fuses act as protection by preventing excess current from damaging the components, while light assemblies are crucial for visibility and safety on the road.

This combination of components is essential in maintaining the overall functionality of the trailer's electrical system. Properly functioning wiring and fuses are vital for safe operation, as they manage the power distribution and protect against shorts or overloads. Light assemblies, which include running lights and turn signals, play a significant role in ensuring that the trailer is visible to other road users, thus enhancing safety during transport.

The other options, while related to various electrical systems, include components that are not primary to a transport trailer's electrical setup. For instance, alternators are more frequently associated with vehicles like trucks rather than trailers, and chargers and insulation are not considered core components of a trailer's electrical framework.
