  • Publication number: 20210347294
    Abstract: When a pedestrian who is crossing a road or is about to cross a road is detected and it is determined that there is a risk of the own vehicle coming into contact with the pedestrian, a figure rendering forming optical unit provided in a housing of a head lamp emits a spot of light having a predetermined width and a predetermined length to a road surface ahead in a crossing direction including the pedestrian or the like. Accordingly, the pedestrian or the like knows the presence of an approaching vehicle and a driver knows the presence of the pedestrian or the like who is crossing a road or is about to cross a road.
