PROBLEM TO BE SOLVED: To provide a vehicle lamp having uniform light distribution pattern.SOLUTION: The vehicle lamp includes a plurality of optical units 15 forming a plurality of light distribution areas, and a light distribution control unit 13 connected to each optical unit. Each optical unit has a plurality of light emitting elements, a light emitting element driving unit 23 for individually supplying a drive signal to each light emitting element, and a practical illuminance storage unit for storing practical illuminance of the light to be emitted when each light emitting element is individually driven under a predetermined condition, for each of the plurality of light emitting elements. The light distribution control unit includes: a correction value computing unit which reads the practical illuminance stored in the practical illuminance storage unit of each optical unit, and computes the correction value for individually correcting the drive signal to be supplied to each light emitting element of each optical unit by using the practical illuminance; a correction value storage unit for storing the correction value for each light emitting element; and a drive control unit for supplying the control signal to a light emitting element drive unit so as to supply the drive signal corrected by using the correction value. |
