Name the components of a trailer’s electrical system.

Brakes, axles, and wheels
Batteries, wiring harnesses, lights, and fuses
Suspension, chassis, and tires
Engine, transmission, and exhaust

The correct answer is: Batteries, wiring harnesses, lights, and fuses

The components of a trailer's electrical system are crucial for ensuring the functionality and safety of the trailer during operation. This includes batteries, which provide the necessary power to the electrical system; wiring harnesses, which connect all the electrical components and facilitate the flow of electricity; lights that serve not only for visibility but also for signaling to other drivers; and fuses that protect the electrical circuits from overloads by breaking the connection if a fault occurs. Each of these components plays a vital role in the operation of a trailer's electrical system, ensuring that everything from brake lights to interior lights operates correctly and safely. This is fundamental for compliance with road safety regulations and for the overall performance of the trailer. The other options presented, while relevant to the operation of a trailer, do not pertain specifically to its electrical system.
