Abstract

L'invention aborde le problème des dispositifs de phares de véhicule classiques qui causent de la fatigue oculaire ou une sensation d'inconfort chez un conducteur. La présente invention comporte : une première unité de phare (2) ; une deuxième unité de phare (3) ; une troisième unité de phare (4) ; une unité de détection (7) ; et une unité de commande (8). L'unité de commande (8) effectue la commande de mise en marche/d'arrêt de la lumière pour au moins l'une parmi la première unité de phare (2), la deuxième unité de phare (3), et la troisième unité de phare (4) selon une commande de gradation d'intensité lumineuse impliquant des changements temporels. En conséquence, la présente invention permet de réduire la fatigue oculaire ou la sensation d'inconfort du conducteur.
