There is room to improve the lighting timing or lighting mode of the projection unit in relation to the lighting of the turn light. A vehicle lamp is provided with: a projection unit (4d) that has a light source (21) and projects predetermined images (5a-5c) onto a road surface on the basis of the lighting of the light source; and a lighting control unit (31) that controls the light source (21). The lighting control unit (31) controls the light source (21). A required period from a first time when the light source (21) starts to light up in accordance with the input of the turn signal or the hazard warning signal to a second time when the light source (21) reaches a target light intensity is ended later than a third time when the turn light or the hazard warning light is lighted up at the target light intensity in accordance with the input of the turn signal or the hazard warning signal.
在与转向灯的点亮的关系中,投影部的点亮定时或点亮方式存在改善的余地。车辆用灯具包括:投影部(4d),其具有光源(21),并且基于该光源的点亮将预定像(5a~5c)投影于路面;以及点亮控制部(31),其对光源(21)进行控制。点亮控制部(31)控制光源(21),使得从光源(21)根据转向信号或危险警告信号的输入而开始点亮的第一时刻到光源(21)达到目标光度的第二时刻为止的所需期间比转向灯或危险警告灯根据转向信号或危险警告信号的输入而以该目标光度点亮的第三时刻晚结束。
