A light module of a lighting device comprises one passing-light sub-module for production of a dimmed-light distribution below a horizontal “light/dark” boundary, one high-beam sub-module for production of a light distribution above the boundary, a common projection-lens system for production of an overall light distribution, and one element deflecting a course of light beams of the sub-module(s) before it falls on the system. To realize the smallest system and a reduction of non-homogeneities in the overall light distribution in a region of the boundary, a majority of the light beams of the high-beam sub-module falls on a common segment of the system as a majority of the light beams of the passing-light sub-module, a smaller portion of the light beams of the high-beam sub-module falls on another segment of the system, and the system exhibits a deflector that deflects at least a portion of the light beams falling on the other segment downward.
