摘要

A motor vehicle lighting unit (BO) comprises at least one main wall (PP) which is equipped with first fixing means and defines part of a first reflector (R1) intended at least partially to perform a first photometric function, and at least part of a zone (R2), situated beside the part of the first reflector (R1) and intended at least partially to perform a second photometric function. This lighting unit (BO) also comprises a metal panel (PM) equipped with second fixing means (MF21) of the elastic type collaborating with the first fixing means in order to secure the metal panel (PM) to the main wall (PP) by pressing it firmly against it under stress in a first direction (D1) and in a position that ensures separation between the first and second photometric functions.
