Abstract

A lamp, in particular a position lamp for a motor vehicle, has a housing in which at least one light source is arranged, with the housing having a light pane covering an opening of the housing, with the light source being structured as a plurality of light-emitting diodes. A light field formed by a plurality of similar first light-emitting diodes to produce a basic light-intensity distribution and at least one additional second light-emitting diode to produce a preferred light-intensity distribution is provided so that a predetermined total light-intensity distribution is obtained by superpositioning, or overlapping, of the basic light-intensity distribution and the preferred light-intensity distribution.
