PCT No. PCT/DE91/00427 Sec. 371 Date Jan. 9, 1992 Sec. 102(e) Date Jan. 9, 1992 PCT Filed May 23, 1991 PCT Pub. No. WO92/00487 PCT Pub. Date Jan. 9, 1992.The vehicle lamp includes a reflector; a light source; and a lens plate having an inner surface facing the reflector and provided with optical elements for deflecting light beams reflected from the reflector. Each of the optical elements is constructed so that the light beams passing therethrough are deflected in each case in a horizontal direction and/or a vertical direction so as to produce a prescribed light distribution identical for all optical elements. Each of the optical elements is subdivided into a number of subprisms having flat surfaces extending tangentially to an envelope of an inner surface of theoptical element. Each of the subprisms is assigned to a region of the light distribution and has a surface determined by an amount of light assigned to the region of the light distribution.
