A vehicle lighting module includes a silicone lens having an input surface and an exit surface, and a light source. The lens defines a near-zero draft between the input surface and the exit surface. The input surface is configured to shape an incident light emanating from the light source into a collimated light pattern emanating from the exit surface and containing at least 69% of the incident light. For this, the input surface includes a plurality of multi-faceted near-field lens elements each having a different focal length and each defining a near-zero draft. The exit surface includes a plurality of micro-optical elements configured to shape the collimated light pattern into a predetermined emitted light pattern.
