To provide a sub headlight unit for use in a vehicle that leans into turns, by which occurrence of a situation where a rider feels uncomfortable about a change in an illumination range can be suppressed. [Solution] A sub headlight unit (13L, 13R) for use in a vehicle (10) that leans into turns, wherein
the sub headlight unit includes a sub headlight light source (13La, 13Lb, 13Lc, 13Ra, 13Rb, 13Rc) that illuminates, at one side with respect to a width direction of the vehicle, an area ahead and outward of the vehicle with respect to the width direction of the vehicle,
the brightness of the sub headlight light source changes in accordance with a lean angle of the vehicle,
when the lean angle of the vehicle leaning to the one side with respect to the width direction of the vehicle reaches a reference value that is set for the sub headlight light source, the sub headlight light source lights up with a first brightness, and in a period from when the lean angle of the vehicle reaches a lower value that is less than the reference value to when the lean angle of the vehicle reaches the reference value, the sub headlight light source lights up with a brightness lower than the first brightness. |
