ABSTRACT:
Apparatus for opening and closing a retractable head lamp which includes a hand operated switch for effecting lighting and unlighting of the head lamp and initiating opening and closing movements of the head lamp, motor for driving a retracting mechanism for opening and closing the head lamp and a detector for detecting a desired position (opened and/or closed) of the head lamp and for selectively stopping energization of the motor when the head lamp reaches a desired position. A control means is connected between the hand switch and the detecting means and is responsive to operation of the hand switch from a lighting position substantially instantaneously to an unlighting position to prevent energization of the motor, thereby preventing closing of the previously opened head lamp. The control means is also responsive to operation of the hand switch from an unlighting position substantially instantaneously to a lighting position thereof to energize the motor and to maintain energization of the motor until the retractable head lamp is driven to its fully opened position, thereby preventing stopping of the retractable head lamp at a partially open position. The control means preferably comprises a transistor switching circuit with an RC timer.
