Abstract

A screen (4) is provided in front of a vehicle (2), and a semi-transparent mirror (3) is provided halfway between the vehicle and the screen. The mirror (3) is inclined at an angle alpha away from the vehicle, and forms a virtual image (10b) of the vehicle headlamp (9b). The line joining the headlamp and its image is inclined at the angle alpha to the horizontal, and defines the required direction of part of the headlamp beam, such as its upper cut-off. The part of the beam which passes through the mirror (3) forms an illumination pattern on the screen (4), and the relative position of this pattern and the virtual image (10b) indicates whether the headlamp alignment is correct. The apparatus is preferably provided at a filling station.
