Description

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention; Fig. 1 is a schematic diagram of the electrical configuration, Fig. 2 is a layout diagram of the optical sensor, Fig. 3 is a flowchart showing the autolight program, and Fig. 4 is a schematic diagram of the light sensor. It is a time chart showing a pattern of dark state detection by a sensor. In the drawings, 1 is a first optical sensor, 2 is a second optical sensor, 3 is a vehicle, 4 is a microcomputer (control means), 5 is a vehicle speed sensor, 6 is an auto switch, and 7 is a light control relay.

Claims (1)

[Scope of utility model registration request] First and second optical sensors are provided at the front and rear of the vehicle to detect the brightness outside the vehicle, and the outside of the vehicle becomes dark based on detection signals from these first and second optical sensors. control means for turning on the vehicle lights when it is determined that the dark state is detected by the first and second optical sensors, and the control means is configured to control the dark state when there is a time difference of more than a predetermined time between the detection of the dark state by the first and second optical sensors; An automatic lighting device for vehicle lights, characterized in that the vehicle lights are turned on when detection continues for a certain period of time or more.
