Abstract
A headlight for dim head lamps of motor vehicles includes a paraboloid reflector which has a glowing spiral, and a transparent pane on the inner surface of which seven fields with differently acting optical means are provided. These fields reflect light rays emitted by the glowing spiral and reflected by predetermined zones of the reflector and form a dimming light.
