    Abstract: A light module for a headlight of a motor vehicle, the light module having: a circuit board having at least one illuminating device for emitting light, wherein the circuit board has a longitudinal extent along a Y-axis, a width extent, extending perpendicular to the longitudinal extent, along an X-axis, and a vertical extent, extending perpendicular to the longitudinal extent and the width extent, along a Z-axis; a reflector; and a heat sink on which the circuit board is fastened. The heat sink is fastened to the reflector via a first fastener in such a manner that the first fastener secures a first referencing structure and/or a second referencing structure of the reflector against the circuit board such that the at least one illuminating device is located in a reference position in the direction of the Y-axis and in the direction of the X-axis relative to the reflector.
