<p>A vehicle lamp (LHL,RHL) is arranged to switch between a low beam and a high beam. The high beam illuminates a first illumination area (SA1), which lies ahead of and square to a center of a vehicle, and a second illumination area (SA2), which includes portions lying horizontally further leftwards and right wards and vertically further upwards than the first illumination area (SA1). When switching from the low beam to the high beam, the luminous intensity of the second illumination area (SA2) is increased and thereafter the luminous intensity of the first illumination area (SA1) is increased. When switching from the high beam to the low beam, the luminance intensity of the first illumination area (SA1) is decreased and thereafter the luminance intensity of the second illumination area (SA2) is decreased.
