Abstract

PURPOSE: To prevent light from keeping lighting-up after a vehicle passes a tunnel by permitting the headlight of the vehicle to be automatically controlled through switching between lighting up and off according to the amount of outside light.
CONSTITUTION: A light receiving element P is installed on a meter panel PB so that the optical axis (h) is directed upward outside a vehicle, through a front glass FG. The amount L of light received is first judged whether it exceeds the predetermined value L0 in a luminous intensity discriminating circuit 100. In case of L>L0, the luminous intensity discrimination output V5 is in high level, and in case of L<L0, the luminous intensity discrimination output V5 is in low level. The alarm of the apparatus for preventing of forgetting of turning off headlight is generated by the logic product output of the wave-form shaping signal of the light receiving element output signal and the reversal signal of the headlight turning-off signal from a signal delaying circuit.
