Abstract: The present invention relates to an improved cord-winding device universally mountable to any front or rear North-American-style license plate bracket, accommodating all electrical devices, which require a 120VAC power supply for a vehicle. The present invention comprises; a housing containing: a reel, a connection box, a male cord housing, a cord hatch and mounting holes, a closure plate and a universal mounting plate. A female receptacle extends from the housing to allow electrical connections to be made in a place away from weather exposure such as engine or rear compartment. The universal license plate cord winder of the present invention can thereby be mounted either from the top or the bottom of housing without compromising the structural integrity of the attachment while maintaining a water tightness required by such a device.
