VEHICLE LIGHTING DEVICE

A vehicle lighting device is provided which evokes caution of the approach of a vehicle at an early stage on the side of pedestrians irrespective of being day or night. A vehicle lighting device includes: a pattern irradiation part which irradiates irradiation light on a lateral irradiation region on a side of a travel path of one's own vehicle in a bright/dark mixed irradiation pattern in which bright regions and dark regions are alternately repeated; a situation recognition device which obtains an output corresponding to a situation of brightness outside of one's own vehicle; and a controller which, when the output of the situation recognition device corresponds to a first situation which is at least a predetermined specific brightness, controls the pattern irradiation part so as to be a first lighting mode which is not turned off.
