Abstract
In the invention, a comparison is carried out within a computer of an item of information relating to a direction of a light beam of a lamp, this item of information being obtained by means of a position sensor, and an item of information relating to an instruction for horizontal displacement of the light beam. If there is not agreement between the two items of information, the computer can then have a degraded operating mode of the lamp adopted by compelling it to orient the light beam downwards in order to remove any risk of dazzling an oncoming driver. To that end, the computer controls a range correction motor in order to bring about a downwards vertical deviation of the light beam.
