Abstract
A vehicle lamp system includes a lamp unit and a lamp control unit. The lamp unit includes a plurality of LEDs and forms a high-beam light-distribution pattern. The lamp control unit controls the on/off of each of the plurality of LEDs. The lamp control unit controls each LED in the following manner. Specifically, the luminance is gradually lowered in a first period when the luminance is lowered to a level at which the LED remains on at reduced luminance. The luminance is gradually lowered in a second period, which is shorter than the first period, when the luminance is lowered to a level at which the LED is off.
