Abstract

La présente invention se rapporte à un dispositif lumineux de véhicule comprenant une source lumineuse (S) à bâtonnets électroluminescents submillimétriques (11, 12) répartis dans une première zone d'émission (1) et dans une deuxième zone d'émission (2), chacune de ces zones étant activable indépendamment, la première zone d'émission étant agencée de manière à être apte à émettre des rayons lumineux (r1, r2) participant à la formation faisceau lumineux (F), et ladite deuxième zone d'émission étant agencée de manière à être apte à émettre un signal de communication.
