A motorcycle light includes a lighting device, having a headlight contained within a housing; a rod configured to engage with a headlight connection of a motorcycle; and one or more wires to engage with an electrical system of the motorcycle; a motor engaged with the housing and to provide rotational movement of the housing relative to the rod; and one or more sensors in electrical communication with the motor and to detect when the motorcycle is at a leaning position, the one or more sensors to provide a command to the motor to rotate the housing to a desired angle for improved visibility.

To provide a lighting apparatus arrangement for a saddle riding vehicle, allowing a predetermined illumination distance and illumination range of laser light to be easily achieved. A lighting apparatus includes a laser device, a first light guide, and a front-portion light emitting unit. The laser device emits laser light. The first light guide guides light from the laser device to any desired position. The front-portion light emitting unit is disposed at a distal end of the first light guide and irradiates areas around a vehicle with light from the first light guide. The front-portion light emitting unit is disposed at a position higher in level than a lower end of a meter unit disposed at a front portion of a vehicle body.

A straddle vehicle which turns in a bank state in which a vehicle body is rotated around an axis extending in a vehicle length direction, includes a head lamp unit which is disposed at a front portion of the straddle vehicle and emits a light beam with which a forward region of the vehicle body is irradiated; a cornering lamp unit which is disposed at the front portion of the straddle vehicle, provided separately from the head lamp unit, and turned on in the bank state; and a duct member included in an engine air-intake system, wherein the cornering lamp unit is disposed below the head lamp unit and below an air-intake inlet of the duct member.

Method for controlling modules for projecting pixelated light beams of a host vehicle. The host vehicle includes a step of determining, using a control device and according to the collected data, a polynomial function which models the profile of the edge and the centre of the road, such that the road profile is modelled based on a polynomial function, the degree of which depends on the curvature of the road. Also included is a step of determining, by means of the control device, a starting point (Pd) and an arrival point (Pa) of an area for projection (ZPd, ZPg, ZP) of patterns, and a step of determining, by means of the control device, a distance (De) between an axis (Ac) of a data/image acquisition means and the patterns, respectively for a right projection area ZPd and a left projection area ZPg. The control device is used to determine the width (Lm) of the pattern.

A bank angle of a vehicle can be accurately calculated using yaw axis data and roll axis data, and based on the calculated bank angle, vehicle illumination optics can be controlled to maintain a pattern of distributed light from the illumination optics to be generally horizontal. The calculated bank angle may be zeroed when the yaw axis data equals zero. The improved pattern of distributed light from the illumination optics illuminates a more natural field of view for the vehicle driver during a bank.

A lighting system for a vehicle having a housing, a plurality of elements generating an intensity of light and a controller. The controller selectively changing the intensity of at least one of the plurality of elements based on a sensed condition.

Provided is a lighting control device capable of reducing the lighting delay when a light source is turned on/off in accordance with the bank angle of a vehicle. The lighting control device which controls the lighting state of the light source sets the time period required for turning on the light source to be shorter as the vehicle speed is higher when the inclination angle of a vehicle body in the vehicle width direction is larger than a reference value, and causes the light source to be fully turned on over the set time period. The lighting control device also sets the time period required for turning off the light source to be shorter as the vehicle speed is higher when the inclination angle of a vehicle body is smaller than a reference value, and causes the light source to be dimmed and turned off over the set time period.
