A vehicle headlight includes a housing and a central area within the housing configured to emit high beam illumination from a high beam light source and configured to emit low beam illumination from a low beam light source. A pair of flow-through vents open to a front side of the housing and open to a rear side of the housing. A pair of outboard areas within the housing include supplementary light sources. The pair of outboard areas are positioned outboard of the pair of flow-through vents of the vehicle headlight.

A headlight device including a headlight configured to emit light frontward of a leaning vehicle to form a lower light beam, an upper central light beam, an upper left light beam and an upper right light beam, and a control device that controls light emission from the headlight without any user operation. The control device forms both the upper left and the upper right light beams while the leaning vehicle is traveling straight, and reduces a brightness of the upper left and upper right light beams, responsive to a vehicle being illuminated by the upper left and upper right light beams respectively, and forms the upper left and upper right light beams respectively while the leaning vehicle is turning left and right, and maintains the brightness of the formed upper left or upper right light beam regardless of whether any vehicle is illuminated by the upper left or upper right light beam.

A headlight includes a housing, a low-beam light source and a high-beam light source, a board, and an upper inner lens and a lower inner lens. The low-beam light source and the high-beam light source are each formed of an LED that is housed in the housing and radiates light. The board controls light beams emitted from the low-beam light source and the high-beam light source. The upper inner lens and the lower inner lens are provided in the housing and allow each of the light beams emitted from the low-beam light source and the high-beam light source to be transmitted through the upper inner lens and the lower inner lens toward the vehicle front side. At least part of the board is disposed to overlap with the rear side of the upper inner lens for the low-beam light source.

A headlight module includes a light source, a light guide element, and a projection optical element. The light source emits light. The light guide element has a reflecting surface for reflecting light emitted from the light source and an emitting surface for emitting light reflected by the reflecting surface. The projection optical element projects light emitted from the emitting surface. In a direction of an optical axis of the projection optical element, an end portion on the emitting surface side of the reflecting surface includes a point located at a focal position of the projection optical element.

A motorcycle lighting system including a plurality of LED light members fixedly embedded within hollow frame members of a motorcycle, a series of wires attached to respective light members and threaded through the interior of the hollow frame members and connected with control members attached to the handle bars of the motorcycle frame such that a rider can control the color and flashing sequences of the light members when in use. The frame can include any known and usual parts including highway bars.

A headlight for a two-wheeled motor vehicle is provided in which disposed in a single housing are a high beam headlamp light source, low beam headlamp light sources that are disposed on the left and right of the high beam headlamp light source, a high beam headlamp reflector, low beam headlamp reflectors that are disposed on left and right sides of the high beam headlamp reflector and are formed integrally with the high beam headlamp reflector, and a position lamp light source, wherein a light guide member that guides light from the position lamp light source and makes the light shine forward is extendingly disposed so as to surround a lateral end, excluding a section adjacent to the high beam headlamp reflector, of the low beam headlamp reflector. This enables visibility and conspicuousness to be improved.

To provide a LED headlight structure that visually conveys a modern or stylish appearance to an observer, the LED headlight structure is characterized in that: a headlight PCB(260) low beam and high beam headlight LED structures on at least one side of the motorcycle are mounted to one plate or in one plane such that high beam illumination is emitted at the inside of the motorcycle and low beam illumination is emitted at the outside of the motorcycle; an extension member (120) is positioned forward of the reflector assembly (140) and between a headlight case (104) and a headlight lens (102); and a window structure (122) configured for selectively passing portions of the low and the high beam illumination reflected by the reflector assembly is formed at the extension member (120).

A headlight module includes a light source, a light guide element, and a projection optical element. The light source emits light. The light guide element has a reflecting surface for reflecting light emitted from the light source and an emitting surface for emitting light reflected by the reflecting surface. The projection optical element projects light emitted from the emitting surface. In a direction of an optical axis of the projection optical element, an end portion on the emitting surface side of the reflecting surface includes a point located at a focal position of the projection optical element.

A saddle-riding vehicle includes a saddle-riding vehicle body and a headlamp unit supported by the vehicle body. The headlamp unit includes: a lamp housing with a cross-sectional shape perpendicular to a front-back direction getting smaller toward a front side; a projector type lamp housed in the lamp housing and including a first LED light source; and a reflector type lamp housed in the lamp housing and including a second LED light source. The projector type lamp is a low beam lamp, and the reflector type lamp is a high beam lamp.
