Abstract: 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.

Abstract: A handlebar switch can include a switch case housing switches, and manipulation members arranged on the switch case and configured to be manipulated by a driver to operate the respective switches. A center portion of the switch case 66 on which the manipulation members are arranged is formed as an expanded section expanded in radial directions of a main body section beyond a right end portion, and a left an end portion of the main body section. The manipulation members are arranged in a center part of the expanded section.

Abstract: A headlight device for a motorcycle that can enhance cooling efficiency inexpensively, without using any special device. In the headlight device for the motorcycle, reflectors are provided with inlet parts through which cooling air is taken into an inside space. In addition, a louver provided on the upper sides of the reflectors is provided, at a position close to an outer lens, with openings through which the air in the inside space is discharged into an inside space.

Abstract: A traction control display device for a vehicle having traction control for suppressing slipping of a wheel in response to operation of an accelerator by a driver. The traction control display device includes a meter and a traction control system (TCS) indicator. The meter has a needle movable over a dial that indicates an engine rotational speed. The TCS indicator indicates that the traction control is in an activated state. The TCS indicator is disposed in a region of parts of high engine rotational speeds within a movable range of the needle within the meter.

Abstract: A headlight device for a motorcycle that is able to emit a light beam in a predetermined shape and in a sufficient light emission amount. The headlight device for the motorcycle includes light guide light sources provided separately from headlight light sources that lights the front side. Light guide members serve to emit a light beam in a predetermined shape, based on light beams emitted from the light guide light sources. In this case, those portions of a first extension at which the light guide members are mounted are configured as reflective parts that reflect forward a rearwardly radiated portion of the light beam emitted from the light guide members.
