A simple lighting issue can result in roadside violations, unsafe driving conditions, or even prevent you from operating legally. That’s why Bergen Diesel offers detailed Lighting, Wiring & Safety Checks that ensure every aspect of your commercial truck or trailer is road-ready. We begin with a thorough walkaround inspection, testing every light—headlights, taillights, brake lights, turn signals, clearance lamps, and marker lights. From there, we move into wiring diagnostics, identifying shorts, damaged connections, or corroded harnesses. If repairs are needed, we use high-grade wiring and connectors to restore complete function and durability.
