Abstract
L'invention concerne un appareil indicateur éclairé, par exemple, pour un tableau de bord de véhicule automobile. L'appareil comprend un cadran 10 transmettant la lumière, une aiguille 42 transmettant la lumière, une première source lumineuse 50 pour l'éclairage du cadran, une seconde source lumineuse 52 pour l'éclairage de l'aiguille, un élément 30 conduisant la lumière de la seconde source vers l'aiguille, et des premier et second moyens 60 et 62 de réglage de l'intensité lumineuse émise par les sources 50 et 52. L'invention concerne notamment les appareils indicateurs d'un tableau de bord de véhicule automobile.
