A headlight control apparatus 1 that controls an illumination state of a headlight 10 that illuminates an area ahead of a vehicle includes an illuminance sensor 21 that detects luminance around the vehicle, an illumination control section 31 that switches on or off the headlight 10 in accordance with the luminance detected by the illuminance sensor 21, a forward detection sensor 22 that detects an object that is present within a predetermined distance ahead of the vehicle, and a dimming control section 32 that dims the headlight 10 when the forward detection sensor 22 detects an object after start of the vehicle.

A vehicle for use in collective zone lighting includes a wireless transceiver and a controller. The controller is configured to create a group of vehicles using wireless messaging, via the wireless transceiver, between the vehicle and one or more other vehicles, and instruct the group of vehicles to collectively light an area using exterior lights of a plurality of the group of vehicles.

A light assembly for a school bus. The light assembly includes a housing having a front side and a rear side, wherein the rear side is mountable to a school bus. The front side of the housing includes a perimeter light, a stop light, and a platform light, wherein the lights can alert vehicles approaching a stopping school bus. The perimeter light is disposed around a perimeter of the housing and can produce an amber color. The stop light includes the word stop in a non-colored transparent material and the platform light, disposed between the perimeter light and the stop light, can produce a red color. In one embodiment, the light assembly is operably connected to a control, speedometer, and door assembly of a school bus, allowing the light assembly to automatically activate when the school bus stops and automatically deactivate when the school bus door closes.

A control device of a vehicle lamp device includes a reception unit and a control unit. The control unit includes a timing determination unit configured to determine a driving timing of an actuator configured to change a posture of the vehicle lamp device. The timing determination unit drives the actuator when an acquisition number of the output values of the acceleration sensor reaches a first number while a vehicle speed is less than a predetermined value, and drives the actuator when the acquisition number of the output values of the acceleration sensor reaches a second number smaller than the first number while the vehicle speed is equal to or greater than the predetermined value.

A method and system for correcting an inclination of headlights of a motor vehicle based on measurements of accelerations of the vehicle supplied by a sensor borne by the motor vehicle. The method and system comprises a step of computing a variation of inclination of the vehicle between a first distinct instant and a second distinct instant defining a duration during which the motor vehicle registers a single stoppage followed by a restart, as a function of the measurements of accelerations, and a step of controlling the inclination of the headlights as a function of a computed variation of inclination of the vehicle.

In a headlight optical-axis control device 10, a controller 15 is configured to: calculate vehicle angles indicating tilt angles of a vehicle relative to a road surface, on the basis of ratios, each being a ratio of a difference between a reference acceleration in a longitudinal direction and a signal indicating an acceleration in the longitudinal direction detected during traveling of the vehicle, to a difference between a reference acceleration in a perpendicular direction and a signal indicating an acceleration in the perpendicular direction detected during traveling of the vehicle by an acceleration sensor 2; calculate a plot of the calculated vehicle angles thereby to derive a vehicle angle corresponding to a case where a change of the acceleration in the longitudinal direction is zero; and generate a signal for controlling the optical axes of headlights 5L and 5R on the basis of the derived vehicle angle.
