  • this can be used to provide a signaling function, for example daytime signaling or to provide an aesthetic function, for example a visual signature function of the motor vehicle.
  • Documents are known FR 2 934 353 , US 2003/147252 and DE 10 2004 056 252 lighting and / or signaling devices for motor vehicles, comprising one or more light sources emitting light rays in one or more light guides which may be in the form of sheets, the light sources being arranged on supports of the type printed circuits.
  • the light is injected into the light guides perpendicular to an end face thereof, which implies that the supports or the integrated circuits themselves are perpendicular to the guides or the sheets.
