ABSTRACT:
The object of the invention is a dual-function lamp device for a motor vehicle, comprising in particular a light source emitting light signals towards an output surface of the lamp in order to produce a light beam, and a filtering means which can move between a passive position and an active position in which it allows passage of only some of the light signals corresponding to non-visible wavelengths, the filtering means being used in association with an intermediate lens for modifying the dispersion of the light beam. The driver thus has a direct illumination and an indirect illumination for obtaining, from a single lamp, two different fields of vision.
