A vehicle headlamp includes a housing, at least one lamp located in the housing, at least one beam alignment light source positioned in the housing and configured to project an image to aid in alignment of the at least one lamp, and at least one beam alignment mechanism operably coupled to the housing and configured to adjust the direction of light from the at least one lamp based on an image projected by the beam alignment light source.

A vehicle may have lights such as headlights. The lights may be moved using a positioner. Control circuitry in the vehicle may use sensor circuitry to monitor the environment surrounding the vehicle. The sensor circuitry may include one or more sensors such as a lidar sensor, radar sensor, image sensor, and/or other sensors to measure the shape of a surface in front of the vehicle and the location of the surface relative to the vehicle. These sensors and/or other sensors in the sensor circuitry also measure headlight illumination on the surface. Based on the known shape of the surface in front of the vehicle and the distance of the surface from the vehicle, the control circuitry can predict where a headlight should be aimed on the surface. By comparing predictions of headlight illumination on the surface to measurements of headlight illumination on the surface, the vehicle can determine how to move the headlight with the positioner to align the headlight.

There is provided an aiming adjustment method for a vehicle headlamp which performs aiming adjustment based on a reference point on a light-dark boundary of a light distribution pattern, the method includes setting, as the reference point, an intersection between a vertical light-dark boundary of a part of multi-divided light distribution patterns which are to be synthesized to form a high-beam light distribution pattern and a horizontal light-dark boundary of a low-beam light distribution pattern.

The present disclosure discusses a lighting apparatus. The lighting apparatus includes a housing with a fastening fixture and a pivot fixture, a light bar including a first arm, a second arm and a third arm with an optical marking, and a light guide including a light pipe, a pivot hole, a first slot and a second slot located between the housing and the light bar, wherein the optical marking of the light bar is aligned with the light pipe of the light guide by rotating the light guide and the first arm about the pivot hole and the light bar is fastened to the housing.

A vehicle headlamp alignment system is provided that includes a headlamp located on a vehicle, an adjuster module for adjusting aim of the headlamp, and a camera located on the vehicle. Sensors may determine distance and orientation of the vehicle relative to a wall. A controller processes images of a beam on the wall acquired by the camera and determines the aim of the headlamp based on the images. The controller controls the adjuster module to align the headlamp based on the determined aim.
