ABSTRACT:
A concealed type head lamp device in which head lamps are provided on a motor vehicle body and are capable of performing exposed, concealed, turning on and off and passing operations by a plurality of switches driven by means of a single operating lever. The head lamp device has a delay circuit by which the head lamps are concealed after a predetermined period of time from turning off of the head lamps to prevent the head lamps from emitting a dazzling beam toward a facing vehicle. The head lamp device has also a temperature sensitive switch for measuring an ambient temperature of a motor vehicle whereby the head lamps are driven to be exposed when the ambient temperature is below a set level for preventing the lamp portions from being freezed.
