The present disclosure relates to a lamp for a vehicle, and more particularly, to a lamp for a vehicle which is capable of preventing occurrence of a blind zone caused by a defect. The lamp includes a light source portion with a plurality of light emitting areas in which brightness of generated light is separately controllable and a brightness controller which is configured to cause the plurality of light emitting areas to generate light at a first brightness level to form a beam pattern and to cause at least one of the light emitting areas, which is disposed proximate to a defective area which includes at least one faulty area, to generate light at a second brightness level.

A headlight system for a vehicle is enabled for a bending light function. A first light module generates a conventional asymmetrical dipped headlight with an upper first light/dark boundary on the driver's side of a central axis. A second light module has a matrix of light-emitting diode units. A control unit actuates light emissions of the individual light-emitting diode units separately. A bend-detection unit detects the radius of a curve in the direction of travel of the vehicle. The light-emitting diode units have at maximum two horizontal lines, and they generate an emission characteristic with a lower second light/dark boundary below the first light/dark boundary of the dipped headlight, an upper third light/dark boundary above the first light/dark boundary of the dipped headlight, and a lateral fourth light/dark boundary on the side of the light emissions of the second light module the faces the driver's side.
