  • An essential object of the invention is to automatically optimize, according to different elements present in the vicinity of the vehicle in question or on the road taken by it, a global light beam produced by a pair of projectors, consisting of a projector right front and a front left projector, or by a pair of optical modules included in the same projector.
  • the adaptation proposed in the invention consists in generating a variation of light intensity in a specific direction, in which is located an obstacle or an opposing vehicle, crossed or followed; the variation considered can be expressed either by highlighting a detected obstacle on which one wishes to attract attention by illuminating more strongly the obstacle considered with respect to its neighborhood in an increase, or by a decrease of the intensity bright, only in the appropriate direction, when it is an opposing vehicle which one does not wish to dazzle the driver.
