Abstract: A method and system are disclosed for controlling a plurality of light modules in a lighting and/or signaling system by deactivating a light emission from at least one of the plurality of light modules in the event of a failure of another of the plurality of light modules. The method or system has a first light module suitable for performing a part of a first regulatory lighting and/or signaling function, and a second light module suitable for performing a part of a second regulatory lighting and/or signaling function separate from the first function. A third light module is also provided for selectively performing at least another part of the first function and at least another part of the second function. Light emission from the first and second light modules is deactivated in the event of failure of the third light module.

Abstract: A method for controlling a lighting and/or signaling system, this system including at least a first light module suitable for performing a part of a first regulatory lighting and/or signaling function; a second light module suitable for performing a part of a second regulatory lighting and/or signaling function separate from the first function; and a third module suitable for selectively performing at least another part of the first function and at least another part of the second function; the method comprising the following step: deactivating the light emission from the first and second modules in the event of failure of the third module.
