Abstract

Un circuit d'éclairage (2) pour le clignotement d'une unité d'émission de lumière (3) ayant plusieurs systèmes de source de lumière (PL1 à PL3) est équipé d'une unité de détection d'anomalie (22) qui génère une information d'anomalie (Sdt, Sdt') lors de la détection d'une anomalie même dans un des différents systèmes de source de lumière (PL1 à PL3), et d'un circuit de maintien (23) qui maintient l'information d'anomalie (Sdt, Sdt') pendant une période où le circuit d'éclairage (2) est alimenté avec un signal de clignotement. Le circuit d'éclairage (2) délivre un ou des courants de commande aux différents systèmes de source de lumière (PL1 à PL3) en fonction du signal de clignotement et cesse de délivrer un ou des courants de commande à tous les systèmes de source de lumière (PL1 à PL3) en fonction de l'information d'anomalie (Sdt, Sdt') qui est maintenue par le circuit de maintien (23).
