Abstract
A vehicle lamp control system is provided which can not only restrict a semiconductor light emitting element from being deteriorated or damaged by sunlight and but also maintain an illumination efficiency of the semiconductor light emitting element. The vehicle lamp control system includes a projection lens, semiconductor light emitting elements disposed near a rear focal point of the projection lens and emit light towards the projection lens, a movable shade which can move between a shading position where the movable shade cuts off light emitted from the semiconductor light emitting elements to be incident on the projection lens and a non-shading position where the movable shade does not cut off light emitting elements to be incident on the projection lens, and a headlamp control unit which executes a control in which the movable shade is moved to the shading position with the semiconductor light emitting elements left switched off.
