An adaptive illuminating headlight is provided. The adaptive illuminating headlight includes a stator structure, a rotor structure, a driver, a light emitting unit, an optical assembly, and a control unit, and is installed on a vehicle for use. The rotor structure is configured to rotate relative to the stator structure and has a carrying surface. The driver is arranged between the stator structure and the rotor structure to drive the rotor structure. The light emitting unit is arranged on the carrying surface to emit an illumination light beam. The optical assembly is configured to allow the illumination light beam to project outwardly so as to produce an illumination pattern. The control unit is configured to control the driver to operate according to a posture change of a vehicle body, such that the light emitting unit is driven by the rotor structure to rotate through a predetermined angle.

A straddle vehicle includes a vehicle body, a headlamp main body, and a driver circuit. The driver circuit drives the headlamp main body. The headlamp main body includes a housing that accommodates a light emission member. The driver circuit is disposed outside the housing.

To provide a saddled vehicle with excellent maintainability despite auxiliary lamps being mounted on a guard member.

The saddled vehicle includes a front pipe which has its middle portion held on a vehicle body frame and has its both ends held on side pipes, and connection members connecting between the front pipe and the side pipes. The connection members are each provided across the front pipe and corresponding one of the side pipes and include a front pipe-side fixing part and aside pipe-side fixing part. An auxiliary lamp is held via a lamp stay which is held across the front pipe-side fixing part and the side pipe-side fixing part.

A cover fastening structure for a motorcycle, including a cover member around a headlight that can be made smaller in size and, at the same time, with highly accurate fastening. The cover fastening structure for the motorcycle includes: a headlight for lighting the front side of the motorcycle; middle cowls as exterior parts for covering lateral sides of the motorcycle; a headlight under cover disposed under the headlight such as to be continuous with the middle cowls; and a center upper cowl disposed rearwardly of the headlight under cover such as to cover the lower side of the headlight. The headlight under cover includes a rearward extending wall fitted to the center upper cowl, and the rearward extending wall is provided with a cutout. The center upper cowl is provided with a solid cylindrical fitting-receiving section. The cutout of the headlight under cover and the fitting-receiving section of the center upper cowl are fastened together by being fitted to each other.

A primary optics for a motorcycle headlamp, wherein the primary optics is a non-imaging primary optics configured to irradiate a segmented light distribution in front of the primary optics, wherein the primary optics includes a plurality of light guiding elements for forming a predetermined segmented light distribution from light of light sources in a main direction. Each light guiding element has a light input surface and a common light output surface, wherein the light guiding elements are arranged in groups, wherein each group includes at least two light guiding elements arranged in juxtaposition along a straight arrangement line orthogonal to the main direction. The light segments generated by the light guiding elements of a group are irradiated in juxtaposition along a straight irradiation line corresponding to and parallel to respective straight arrangement line of the respective group. The common light output surface includes a homogenization structure, which is formed of a plurality of grooves, each of which extends along an extension line transverse to the straight arrangement line of each group of light guiding elements, wherein the groove has a constant radius in a cross-section orthogonal to the extension line along the extension line, and wherein the grooves are arranged with respect to each other such that the extension lines of the grooves are parallel to each other.
