Vehicle lamp
A vehicle lamp includes a projector lens, a first light source disposed behind the projector lens and configured to emit light for forming a low-beam light distribution pattern, a second light source disposed behind the projector lens and configured to emit light for forming an additional high-beam light distribution pattern, and a metal base member. The base member includes a first surface on which the first light source is disposed and a second surface on which the second light source is disposed. The second surface is inclined with respect to an optical axis such that an emission portion of the light emitting element faces obliquely forward and upward. A plurality of metal plate-shaped fins extending in a left-right direction and an upper-lower direction of the lamp are arranged along a front-rear direction of the lamp on a rear surface of the first and second surfaces.

SYSTEMS AND METHODS FOR ILLUMINATION CONTROL AND DISTRIBUTION DURING A VEHICLE BANK
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.
VEHICLE FRONT LIGHTING APPARATUS
A vehicle front lighting apparatus includes a lighting device array in which a plurality of lighting devices are connected in series, a plurality of bypass circuits, a plurality of switch elements, a lighting controller, a current value detector, a voltage value controller, and a disconnection determiner. The voltage value controller applies a voltage to the lighting device array, and controls a voltage value to be applied to cause a value of current flowing through the lighting device array to reach a predetermined target current value. The disconnection determiner determines that there is a disconnection in any of the bypass circuits when the number of the switch elements brought into the opened state does not match the controlled voltage value.
