ABSTRACT:
A light signaling device related to the operating state of a system has at least one light and circuits of detection of a failure of this or these lights, in which each light comprises m branches in parallel each composed of n light emitting diodes in series, and a branch selector; where m and n are integers such that m≧2 and n≧1. This invention also relates to a process for management of such device.
