Has anyone ever experienced their headlights and all their marker lights going out on their truck or specifically a Freightliner Coronado? It happens randomly and there seems to be no specific pattern to it. I have never had this issue when bobtailling. It always happens when a trailer is hooked to the truck. I also loose running lights on the trailer when this problem occurs. I still have turn signals and brake lights, on the truck and trailer. The issue could last a few hours or a handful…
