Claim:
1. A device for attenuating electromagnetic disturbances given off by at least one electronic component, arranged on a printed circuit board which is mounted on a first face of a board support and which bears at least one light-emitting diode driven by said at least one electronic component for the emission of light rays, said device comprising an electromagnetic wave containment cage arranged around said at least said electronic component, wherein said electromagnetic wave containment cage is formed partially by containment walls made of a piece with said first face of said board support and on which said printed circuit board rests, so as to delimit, in said board support and on said printed circuit board, a wave containment zone, said wave containment zone having an opening, in a first direction, suitable for being blocked, according to the attenuation needs of said device, by a closure piece distinct from said containment walls.
