A headlight for motor vehicles includes a reflector, a light source, a screen and a lens. The screen includes a screen edge which has two stepped portions. A distance y1 between a part of the screen edge on a side of the less distant road edge and a central part of the screen edge is in a range defined as follows: y1=(0.005 to 0.026)x(xF+d/3) wherein xF is the distance between the screen and the lens, and d is the thickness of the lens. A distance Y2 between the central part of the screen edge and a part of the screen edge on a side of the more distant road edge is such that the total distance y1+Y2 is in a range defined as follows: y1+Y2=(0.008 to 0.044)x(xF+d/3). The headlights according to the invention have improved luminous intensity of the dipped beam on the side of the road of the nearer road edge.
