A system for selectively extending and retracting a license plate holder, the system comprising: a housing comprising a slide rail attachable to a vehicle; a threaded driver disposed within the slide rail and operably coupled to a motor for selectively rotating the threaded driver in a first rotational direction or a generally opposite second rotational direction; a first slider slidably disposed within the slide rail and operably coupled to the driver so as to move in a first and a second generally opposite directions along a length of the driver as the driver is rotated; a license plate mount pivotally attached to the first slider; wherein when the driver is rotated in the first rotational direction, the first slider moves in the first direction a predetermined distance and the license plate mount pivots to an extended position; and wherein when the driver is rotated in the generally opposite second rotational direction, the first slider is moved in the second direction and the license plate mount pivots to a retracted position, characterized in that the system comprises: a second slider disposed within the slide rail in spaced relation to the first slider and operably coupled to the driver to move in the first and second generally opposite directions along a length of the driver as the driver is rotated; and a spring disposed between the first and second sliders (148, 150) for biasing the first and second sliders (148,150) in spaced relation to one another. a housing comprising a slide rail attachable to a vehicle; a threaded driver disposed within the slide rail and operably coupled to a motor for selectively rotating the threaded driver in a first rotational direction or a generally opposite second rotational direction; a first slider slidably disposed within the slide rail and operably coupled to the driver so as to move in a first and a second generally opposite directions along a length of the driver as the driver is rotated; a license plate mount pivotally attached to the first slider; wherein when the driver is rotated in the first rotational direction, the first slider moves in the first direction a predetermined distance and the license plate mount pivots to an extended position; and wherein when the driver is rotated in the generally opposite second rotational direction, the first slider is moved in the second direction and the license plate mount pivots to a retracted position, characterized in that the system comprises: a second slider disposed within the slide rail in spaced relation to the first slider and operably coupled to the driver to move in the first and second generally opposite directions along a length of the driver as the driver is rotated; and a spring disposed between the first and second sliders (148, 150) for biasing the first and second sliders (148,150) in spaced relation to one another. a second slider disposed within the slide rail in spaced relation to the first slider and operably coupled to the driver to move in the first and second generally opposite directions along a length of the driver as the driver is rotated; and a spring disposed between the first and second sliders (148, 150) for biasing the first and second sliders (148,150) in spaced relation to one another.
