A lighting device for a vehicle includes a light emission units, a control device, and an operating unit to be operated when the vehicle is started. The control device increases an emission intensity of light emission units in a first period. The first period includes a second period including a plurality of time intervals. The control device changes the emission intensity of light emission units in each time interval of the second period so that two light emission units in at least one pair of light emission units adjacent to each other differ from each other in light emission parameters. The light emission parameters include at least two parameters out of a magnitude of changing amount in emission intensity in the time interval, a direction indicating whether the emission intensity is increasing or decreasing in the time interval, and the emission intensity at an end point of the time interval.

Lighting device for vehicle

A vehicle headlight control device includes: an indicator value acquiring unit configured to acquire an indicator value that represents a brightness of an object detected ahead of an own vehicle; a light distribution control unit configured to control a light distribution of a headlight such that a quantity of light irradiated to the irradiation region where a dimming target object is present is reduced when the dimming target object is detected, the dimming target object being an object of which the indicator value is greater than a reference value; a reference-value varying unit configured to set the reference value to a first reference value when the object is detected within the gaze area and set the reference value to a second reference value that is greater than the first reference value when the object is detected outside of the gaze area.

Vehicle headlight control device, vehicle headlight control method, non-transitory storage medium

A control unit of a headlamp control device for a vehicle is configured so that, when an occupant of the vehicle performs a predetermined interruption operation while the illumination mode of a headlamp is a high beam mode during automatic illumination control, the control unit sets the illumination mode to a low beam mode until an interruption time passes. The interruption time is set to a smaller value as a vehicle speed correlation value is larger. The vehicle speed correlation value is a value that increases as a speed at which the vehicle has been traveling since the start of the interruption operation is higher.
