发明名称 Trailer towing connector with lighting circuit ground path
摘要 An apparatus provides for coupling a trailer lighting circuit including a light emitting diode to towing vehicle lighting circuit. The apparatus includes a connector having a first contact for coupling to a trailer lighting circuit input and a second contact for coupling to an electrical ground. The connector includes a resistive component coupled between the first contact and the second contact. The connector is configured to couple the first terminal to an output of the towing vehicle lighting circuit. The resistive component can include a resistor, an incandescent light or another component having suitable electrical resistance. The connector can be in various forms, including a trailer harness plug, a towing vehicle harness plug, or an adapter for coupling a towing vehicle electrical harness plug to a trailer electrical harness plug.
