1. A light module for a headlight of a motor vehicle, the light module comprising:
a circuit board having at least one illuminating device to emit 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 being fastened to the reflector via a first fastener such 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,
wherein a position at which the first fastener fastens the heat sink to the reflector is offset from a position of each of the first referencing structure and/or the second referencing structure, such that the first fastener is spaced apart from each of the first referencing structure and/or the second referencing structure, and
wherein the circuit board is fastened to the heat sink by at least one second fastener such that the at least one illuminating device is located in the reference position in the direction along the Z-axis relative to the reflector, wherein the at least one second fastener has a different structure than the first fastener, the first referencing structure and the second referencing structure.
