Abstract
An electrical trailer plug device for connecting a trailer electrical system to a tow vehicle electrical system. The trailer plug device includes a first electrical connector configured to connect an electrical current path of the vehicle electrical system to an electrical current path of the trailer electrical system to complete an electrical circuit supplying electricity from the vehicle electrical system to one or more trailer lamps supported on the trailer. The device also includes a current protection device configured to limit current in the circuit when current flow in the circuit exceeds a predetermined value. A first sensor light is connected in the circuit with a combination of circuit elements configured to illuminate the first sensor light when current is flowing in the circuit but has not exceeded the predetermined. A second sensor light may be connected in the circuit with a combination of circuit elements configured to illuminate the second sensor light when the current protection device is limiting current flow in the circuit.
