In modern trailers (especially commercial ones), terminal blocks are the central connection point for the lighting and electrical system. They are mounted inside a junction box, connecting the power supplied by the tractor unit to the trailer's brake lights, turn signals, tail lights, marker lights, and ABS. The blocks must handle constant road vibration and weather changes, preventing light flickering or failure, which is critical for road safety. Spring-cage terminals are increasingly popular due to their superior vibration resistance. They also simplify troubleshooting and repair, allowing technicians to quickly test or replace individual circuits without dealing with complex wiring harnesses.
