ABSTRACT:
A shroud attachment for use in combination with a warning device, the device including a panel having at least one orifice; a lamp having a portion thereof clearance received within the orifice and having another portion thereof abutted against the face of the panel about the periphery of the orifice. The shroud attachment of the instant invention includes a tubular shroud and a shroud carrier. One end of the shroud is positioned to abut a portion of a lamp which is mounted on a panel of a warning device such that the shroud retains the lamp on the panel. The shroud carrier, in turn, affixes the shroud to the panel. The carrier has a collar portion fitted about the periphery of one end of the shroud and a flange portion extending about the collar portion. The flange portion is substantially normal to the collar portion and attaches the shroud carrier to the panel.
