A light source (14) is configured to emit light for lighting a predetermined area. A LiDAR sensor (15) is configured to sense information of an outside of a vehicle. A first screw mechanism (16) is configured to adjust posture of the light source (14). A second screw mechanism (17) is configured to adjust posture of the LiDAR sensor (15). Adjustment by one of the first screw mechanism (16) and the second screw mechanism (17) is performed on the basis of adjustment that has been performed by the other one of the first screw mechanism (16) and the second screw mechanism (17).

The invention describes a method of analyzing a light distribution of a vehicle headlight. The method determines a cutoff line based on a brightness distribution within a column of an image of the light distribution, the column being perpendicular to a horizon in the image. The method compares the cutoff line with a reference cutoff line and uses the deviations revealed by such comparison to attribute a reduced quality of the light distribution to a particular one of several possible causes. The invention further describes a vehicle headlight analyzer which is arranged to perform the method. The invention finally describes a corresponding computer program product comprising code for executing the method on a processing device.

A method to automate detection of a vehicle light degradation or failure includes generating a distinct pattern to be executed by at least one vehicle light, and sending a command to a light control module operative to cause the at least one vehicle light to emit the distinct pattern. The method continues with extracting features from camera images of the distinct pattern emitted by the at least one vehicle light, and then comparing the features extracted from the camera images with features from the commanded distinct pattern to determine degradation or failure of the at least one vehicle light's state of health.

A vehicle (9) headlight measurement system instrumentation structure (1) comprises: a support structure (3); a vehicle calibration assistance structure (4), which is carried by the support structure (3) and includes a headlight aiming device (40), configured to facilitate alignment or calibration of a headlight (90) of the vehicle (9), the vehicle (9) being positioned within a service area (8); a processing system (11) configured to receive, from the headlight aiming device (40), data correlated with a light beam emitted by the headlight (90) and to provide, through an interface (10), an informative indication relating to an operating condition of the headlight (90), where the processing system (11) includes a communication port (12) connectable to an electronic control unit (91) of the vehicle (9).

A system for aiming a headlamp of a vehicle includes a displaceable aiming surface and an imaging system. The imaging system includes a translatable aim box carrying at least one headlamp imager oriented to capture images of a single headlamp and/or one or more vehicle features adjacent to the single headlamp. At least one fixed imager is oriented to capture one or more images of the displaceable aiming surface. The translatable aim box may be configured to translate between the single headlamp and another headlamp. One or more computing devices are configured to perform methods for headlamp aim correction using the described system. Methods for headlamp aim correction are described.
