Original Abstract Submitted

A vehicle lamp that includes: a light source that emits light due to a drive current that is supplied from a light source drive circuit; and a temperature sensor that measures a temperature of the light source or surroundings of the light source, wherein the light source drive circuit reduces the drive current when the temperature that has been measured by the temperature sensor becomes equal to or greater than a control start temperature, and, in a case in which an illuminance of surroundings of a vehicle that has been measured by an illuminance measurement sensor is equal to or greater than an illuminance threshold, the control start temperature is set to be lower than in a case in which the illuminance of the surroundings of the vehicle is less than the illuminance threshold.
