Disclosed herein is a vehicle headlight for improving visibility during operation. In the vehicle headlight, a filtering film capable of preventing glare and reducing a discomfort glare phenomenon by controlling scotopic vision (S)/photopic vision (P) ratio in such a manner as to selectively absorb/block blue light in light emitted from an LED module is adhered, thereby improving visibility during operation.

Vehicle lighting system

A method for operating a vehicle comprising at least one light source designed to emit light for illuminating the surroundings of the vehicle is described. The method comprises the following steps: determining whether a road user approaches the vehicle to within a predetermined distance; determining the distance between the road user and the vehicle; and illuminating the surroundings of the vehicle by use of the at least one light source at the side of the vehicle from which the road user approaches the vehicle should the distance between the road user and the vehicle drop below a first threshold distance.

Headlight optical-axis control device

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.
