ABSTRACT:
The movable reflector of the headlight of a motor vehicle can be orientated by means of an orientation adjustment device located inside the body of the headlight. The orientation of the reflected light beam is controlled with the help of an adjustable graduated scale which is connected to the reflector and which can move with respect to a stationary indicator fixed to the headlight, so as to indicate the changes in orientation of the reflector. The graduated scale is set to zero by means of a manual adjustment carried out by specialized personnel using a special tool, once the reflector has been correctly orientated by means of the adjustment device. The stationary indicator and the graduated scale are located so that they are clearly visible inside the headlight, beneath the transparent cover of a porthole which can be opened in order to set the scale to zero. In a modified version of the control device, the graduated scale is stationary and is mounted on the inside of the transparent cover so that it cannot be removed. A movable indicator, connected to the reflector, slides along the scale indicating the changes in orientation of the reflector. The graduated scale is set to zero by inserting the special tool through a hole in the cover.
