A control device of a leaning vehicle for controlling bright lighting and dim lighting for a plurality of oblique areas. When the leaning vehicle is upright, the control device controls the lighting by designating one or more of the plurality of oblique areas as in a brightly lit area to which adaptive lighting control is applied, and by designating the other oblique areas as in a dim area. The dim area includes an uppermost oblique area. When the leaning vehicle turns left or right, as a lean angle in a direction of the turn increases, the control device controls the lighting by designating a second uppermost oblique area that is located immediately below the uppermost oblique area in the up-down direction as in the brightly lit area, and moving the uppermost oblique area from the dim area to the brightly lit area.

Headlight device and leaning vehicle

A headlight device includes a headlight and a control device. The headlight includes a plurality of light sources that is configured to light one or more left oblique areas located in the ahead-driving direction of the leaning vehicle on the left, one or more right oblique areas located in the ahead-driving direction of the leaning vehicle on the right, and one or more lower areas located in the ahead-driving direction of the leaning vehicle. The control device controls the headlight to light at least the left oblique areas and the right oblique areas based on adaptive lighting control. At least one of the left oblique areas and at least one of the right oblique areas that are lit based on the adaptive lighting control spread more outwardly in a left-right direction than any of the lower areas.

A first inclined surface and a second inclined surface are inclined with respect to an optical axis of a light emitting diode. The first inclined surface guides light from the light emitting diode guided in the first light transmitting portion toward an outside of an outer lens. An inclination angle of the second inclined surface with respect to the optical axis is larger than an inclination angle of the first inclined surface with respect to the optical axis. The second inclined surface reflects the light from the light emitting diode guided in the first light transmitting portion toward the second light transmitting portion and guides the light into the second light transmitting portion.
