Alternatively, the light incident portion comprises an ILIS and at least one HBLIS, in which the ILIS is either a flat surface, a curved cylindrical body protruding backwards, a hemispherical body protruding backwards, or a light condensing structure. The ILIS is adapted to receive auxiliary lighting light during low-beam lighting. The ILIS is provided on the VLOE, such that when a vehicle light is in a low-beam lighting mode, the VLOE is also luminous, thereby improving the aesthetic appearance of the vehicle light.

A headlight control system has a headlight including a plurality of LED light sources, a camera and a radar that detect a predetermined target object present ahead of a vehicle, and a controller configured to control the headlight such that, when the target object is present, of the plurality of LED light sources, the LED light source irradiating a region where the target object is present is turned off, and such that, thereafter, when the target object is no longer present in the region, the turned-off LED light source is turned on again. The controller controls the headlight such that, at the time of turning on the turned-off LED light source again, a change rate of luminance of the LED light source is changed according to a position of an irradiation region of the LED light source.
