Abstract

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.
