A vehicle lighting unit (10) can reduce the load applied to the actuator (31, 32, 51, 52) for driving a reflecting member (2) as well as can improve the durability of the actuator (31, 32, 51, 52). The vehicle lighting unit (10) can include a light source, a reflecting member (2) configured to reflect light from the light source (11) toward an illumination area, an actuator (31, 32, 51, 52) including inner piezoelectric actuators (31, 32) and outer piezoelectric actuators (51, 52) configured to cause the reflecting member (2) to swing (turn) around X and Y axes simultaneously, to thereby scan the illumination area with the reflected light from the reflecting member (2) horizontally and vertically, and a controller (12) configured to control the inner piezoelectric actuators (31, 32) and the outer piezoelectric actuators (51, 52) such that a scanning frequency in the vertical direction of the reflected light becomes larger than a scanning frequency in the horizontal direction of the reflected light.
