L'appareil d'éclairage à pare-lumière comprend : un module de source de lumière ayant une source de lumière à diode électroluminescente (DEL) et une lentille de collimateur couplée à une surface d'émission de la source de lumière à DEL; un cadre de support ayant le module de source de lumière disposé sur une partie d'extrémité de celui-ci; un premier module optique d'imagerie disposé sur la partie centrale du cadre de support; un second module optique d'imagerie disposé sur l'autre partie d'extrémité du cadre de support; une plaque rotative disposée entre le module de source de lumière et le premier module optique d'imagerie; et un moteur relié à un arbre rotatif de la plaque rotative et disposé sur le module de source de lumière au moyen du cadre de support, la relation de placement entre le premier module optique d'imagerie et le second module optique d'imagerie étant déterminée sur la base de la taille d'image de pare-lumière, d'un filtre d'image de pare-lumière disposé de manière détachable sur une ouverture de la plaque rotative, et de la taille d'une image de projection à afficher sur la route.
