A method for forming a light beam, and a light assembly having at least one light source with a fixed reflector which directs a beam of light light assembly having a front lens, and a light deflecting mechanism for changing the light angle of the light beam after passing through the front lens. The front lens has a central part that differs from the surrounding parts of the front lens, and the light deflecting mechanism, in a first position, concentrates the light beam into the central part of the front lens to generate a wide-angle light beam, and in a second position, distributes the light beam over the entire front lens to generate a narrow angle light beam. The light deflecting mechanism is connected with a first actuator, and is movable between the first and the second position.
