Abstract
A vehicle lamp system includes a high-beam lamp unit that can form a high-beam light-distribution pattern, a leveling mechanism that vertically adjusts an optical axis of the high-beam lamp unit, and a control unit that controls on/off of the high-beam lamp unit and controls the leveling mechanism. Upon the engine being started, the control unit controls the high-beam lamp unit to turn on for a predetermined period of time in a state in which the leveling unit adjusts the optical axis of the lamp unit to aim more vertically downward than in normal operation.
