1. A lighting module for generating two different lighting effects, the lighting module comprising:
at least one light source,
a first primary optical element including a diffusion surface diffusing light from the at least one light source, the first primary optical element also including a first reflector and second reflector,
a second primary optical element, and
a projection lens, wherein the light diffused by the first primary optical element homogenously lights the projections lens for a first lighting effect,
wherein the first reflector reflects light beams from the at least one light source in a boundary area of the first primary optical element onto the second reflector to direct said light beams through the diffusion surface onto the projection lens,
wherein the second primary optical element directs light beams from the at least one light source onto the projection lens to light the projection lens for a second lighting effect, and
wherein the lighting module directs light beams from the at least one light source exclusively through the first primary optical element for the low beam effect and directs light beams from the at least one light source exclusively through the second primary optical element for the high beam effect.
