Abstract (en)
The device has a set of lights (29) and a detection unit that checks for failure of the lights. Each light has m branches (31) with n serially connected light emitting diodes (32) in each branch. The inputs of the diodes are parallel connected and the outputs are connected to a selector (33). The selector connects the selected branch to the output terminal upon receiving signal from a controller (41). <??>An Independent claim is also included for a process for management of a light signaling device related to the operating state of a system.
