Abstract

A beam light unit for vehicles, having a light module with a light source and a reflector, includes a downstream light output element to produce a predetermined light distribution. The light output element is mounted in a housing that leaves only a light outlet face of the light output element exposed, with sidewalls of the housing being in contact with jacket walls of the light output element immediately adjacent the light outlet face. Edge contours of the sidewalls correspond to a form of an edge of the light outlet face.
