Abstract

A light module for a lighting device of a vehicle is disclosed having at least one illuminant and a light-guiding body which is suitable and destined for guiding radiation emanating from the illuminant and coupled into the light-guiding body to a light exit surface of the light-guiding body, and having at least one rear wall apparatus which is arranged at least in certain areas in the beam path of ambient radiation incident from externally through the light exit surface of the light-guiding body into the light-guiding body. The rear wall apparatus has at least one first rear wall region and at least one second rear wall region, wherein the at least one first rear wall region and the at least one second rear wall region differ from one another in terms of reflection and/or absorption properties, for example with regard to the ambient radiation.
