Abstract: A vehicle lamp includes: a first light source configured to irradiate visible light; a second light source configured to emit infrared light; a rotating reflector configured to be rotated while reflecting the visible light and the infrared light, and scan the visible light and the infrared light along a horizontal direction on a virtual vertical screen; a light receiving unit configured to receive the infrared light emitted from the second light source and reflected by a target object; and a controller configured to control an irradiation area of the visible light based on the infrared light received by the receiving unit. When determined that there is an abnormality in at least one of the second light source or the light receiving unit, the controller is configured to control the irradiation area based on the surrounding information of the vehicle obtained from outside the vehicle lamp.
