A vehicle lighting control device includes: a control determination unit that determines whether or not a state of a vehicle is a control target state in which an arrival time required for the vehicle to arrive at a tunnel is less than a predetermined reference arrival time; and a lighting controller that executes a first control to control a headlight to a low beam when a forward vehicle is detected and to control the headlight to a high beam when the forward vehicle is not detected. The lighting controller is configured to prevent the headlight from being switched to the high beam in the first control when determination is made that the vehicle is in the control target state even when a state in which the forward vehicle is detected is changed to a state in which the forward vehicle is not detected.

In an optical sensor, a detecting part includes detecting elements, and a light-shielding portion providing directional characteristics of light to the detecting elements such that the detecting elements indicate different intensities of light received in a specified direction. A signal processing part has an adjustment value for processing detection signals. The adjustment value is set as follows. Based on information of an inclination angle of a window glass of a vehicle to which the detecting part is attached, from the detecting elements, a detecting element having a directional characteristic of light suitable for the inclination angle is selected. The adjustment value is then set so as to coincide a signal value of a detection signal of the selected detecting element with a target value, when the detecting part is irradiated with light in a predetermined direction in a state where the detecting part is inclined at the inclination angle.
