Abstract

L'invention concerne un phare (1) pour véhicules comportant un cadre porteur (3) et une pluralité de sources lumineuses (4) fixées sur le cadre porteur (3). Les sources lumineuses (4) de ce phare sont disposées de façon à pouvoir être mises en circuit et hors circuit de manière groupée pour réaliser un certain nombre de fonctions lumineuses. Dans ce phare, il est prévu une pluralité de modules lumineux (2, 12) présentant respectivement au moins une source lumineuse (4), qui sont disposés de manière à pouvoir être déplacés les uns par rapport aux autres pour le réglage de la limite de clarté-obscurité prescrite.
