A vehicle front structure for a straddle-type vehicle is provided. The straddle-type vehicle includes a headlight installed in a vehicle front. The vehicle front structure includes: a front cowl configured to cover a periphery of the headlight; and a terminal device installed inside the front cowl. The terminal device includes a connection terminal configured to allow insertion or removal of a terminal of an external device, and a controller configured to control communication with the external device. The connection terminal and the controller are mounted inside the front cowl so as to be spaced apart from each other.

A lamp unit for illuminating a front through an outer lens includes a first light source disposed on a back side of the outer lens, a second light source disposed on the back side of the outer lens, a first light guide body configured to guide light from the first light source to the outer lens, and a second light guide body configured to guide light from the second light source to the outer lens. The second light guide body overlaps the first light guide body from a front side in a front view. The first light guide body protrudes outward from the second light guide body. A part of light from the first light guide body is transmitted through the second light guide body and guided to the outer lens.

A vehicle headlight device 100 includes a light source 11, a Dove prism 40, and a rotation mechanism 50. The light source 11 emits light. The Dove prism 40 changes a propagation direction of light received at an incidence surface 401 to bring the light to a reflecting surface 402, and changes a propagation direction of light reflected at the reflecting surface 402 to output the light from an exit surface 403. The rotation mechanism 50 rotatably supports the Dove prism 40 about a line which passes through the incidence surface 401 and the exit surface 403 as an axis of rotation R, and rotates the Dove prism 40 in a direction opposite to a bank direction of a vehicle body in accordance with a bank angle k of the vehicle body.

A headlamp assembly for a saddle-type vehicle includes left and right light-emitting portions arranged on left and right sides, respectively, of a housing. Each of the light-emitting portions includes a light source and a concave reflector, disposed proximate the light source for reflecting light forwardly. Each reflector has an inclined surface configured such that the rear surfaces of the reflectors extend in directions separating from each other as the reflectors extend rearwardly. A driver for driving the light sources of the left and right light-emitting portions is arranged behind and in between the left and right reflectors.

A lighting device includes a housing including a front opening portion and a rear opening portion; a light source unit including LED light sources and a heat sink configured to absorb and radiate heat produced by the LED light source; a socket formed by an elastic member and configured to allow the heat sink to be fitted and supported in the rear opening portion such that part of the heat sink is exposed rearward through the rear opening portion and that aiming adjustment is enabled by changing a position of the light source unit relative to the housing. A knob used for manually turning an adjustment screw is attached to a rear end portion of the adjustment screw, and the socket is provided with a rib extending along a circumferential direction of the socket and protruding rearward of the heat sink.

A headlight structure for ensuring easy structural designing of a light guide member to enhance the degree of the freedom of shape. Reflectors and left and right lenses are disposed respectively on the left and right sides of the center of a vehicle body. Second light sources are attached respectively to the left and right of a light guide member which is roughly W-shaped. Attachment portions and connection portions are hidden by a light-blocking light cover. The left and right reflectors and left and right including shining portions that are visible through the lenses wherein light evenness can be enhanced within an externally visible region. The headlight can be easily enlarged in size and in diameter. The second light sources make it is easy to design the structure of the light guide member for enhancing the degree of the freedom of shape.

A headlight device for a motorcycle that enables substrates with LED light sources mounted thereon to be disposed efficiently while securing such required functions as the external appearance quality of a shape like eyes that are turned up at the corners, light distribution characteristics, etc. In the headlight device for the motorcycle, a plurality of reflectors provided correspondingly to a plurality of substrates having headlight light sources mounted thereon are disposed in such shapes so as to be turned up, like eyes that are turned up at the corners, in a direction away from a center line in an external view. Each of upper surface parts of the reflectors is substantially horizontal and is in a stepped form relative to the adjacent upper surface part. The substrates are disposed substantially horizontally at the upper surface parts.

A saddle type vehicle is provided wherein the visibility thereof can be improved. The saddle type vehicle includes a headlamp configured to illuminate the front of the vehicle and position lamps configured to emit light for the visibility of the vehicle or act as blinkers. The position lamps are disposed in a left and right pair in front of the headlamp. Further, the left and right position lamps are disposed in such a manner as to sandwich the headlamp therebetween as viewed in front elevation.

A vehicle lamp includes a first semiconductor light emitting device, a second semiconductor light emitting device and a heat sink having a device mounting portion on which the first semiconductor light emitting device and the second semiconductor light emitting device are mounted. The heat sink is formed so as to define a lamp compartment which the first semiconductor light emitting device and the second semiconductor light emitting device face and a space which is defined outside the lamp compartment. The device mounting portion has a first device disposing surface and a second device disposing surface on which the first semiconductor light emitting device and the second semiconductor light emitting device are disposed, respectively, and a recess portion which defines a space which is opened towards the space defined outside the lamp compartment.
