A motor vehicle lamp is presented, having an elongated waveguide, which is configured to conduct light in its interior, via total internal reflection occurring on border surfaces of the waveguide, along a guidance line of the waveguide, predefined by the external shape of the waveguide and running inside the waveguide, wherein the waveguide has a light exit surface. The lamp is distinguished in that it has a focusing element, which lies in the light path of the light emitted via the light exit surface, and extends thereby over the entire length of the light exit surface, and is configured to reduce the beam width of the light bundle in which the light emitted from the light exit surface is propagated.
