1. A light guide module for a primary optical assembly of a motor vehicle lighting device, the light guide module comprising:
at least two elongated light guide segments arranged next to one another, each of the at least two light guide segments having a proximal end with a light coupling face and a distal end, the distal ends of the light guide segments leading into a light exit face of the light guide module and a length of the light guide segments being defined by a distance between the proximal end and the distal end; and
a collar that extends at least in sections around the light exit face,
wherein the collar has a local height that corresponds substantially to a length of the respective light guide segment nearest adjacent to the collar,
wherein the local height is defined by a distance between a proximal end section of the collar and a distal end section of the collar, with the proximal end section of the collar being a protruding flange, and
wherein the proximal ends of the light guide segments extend beyond the protruding flange of the collar.
