Abstract
A motor vehicle headlight has a reflector with two focal regions, a light source in one of these focal regions producing a pool of reflected light in the other focal region, and a lens which converts the pool of light into a beam projected on the road. The headlight includes means for displacing the light source with respect to the reflector.
