1. A holding arrangement for lenses of a lighting device for vehicles with at least two lenses that are arranged axially spaced from one another along an axis, the holding arrangement comprising:
a surrounding body enclosing the at least two lenses, the surrounding body comprising two half shells firmly connected to one another, the two half shells including a first half shell that surrounds a first portion of an outer circumference of each lens of the at least two lenses and a second half shell that surrounds a remaining portion of the outer circumference of each lens of the at least two lenses, the surrounding body being formed of a plastic material, the surrounding body having an axial length and a holder such that a light source unit of the lighting device is enclosed in a rear end region of the surrounding body to form a light module,
wherein the plastic material includes a thermoplastic material, a thermosetting plastic material or a composite plastic material, and at least one thermal expansion-reducing additional material,
wherein the plastic material includes the thermoplastic material and wherein the at least one thermal expansion-reducing additional material is a fiber material,
wherein fibers of the fiber material are oriented to run predominantly in an axial direction of the surrounding body,
wherein the light source unit includes a printed circuit board with at least one light source mounted thereon,
wherein an inner surface of each of the two half shells has a recess, the recess of each of the two half shells forming a part of the holder, and
wherein the printed circuit board is partially inserted into the recess of each of the two half shells to hold the light source unit in the rear end region of the surrounding body.
