Abstract: An assembly includes a common parts sub-assembly, an actuator, a physical appendage, and a mounting bracket. The common parts sub-assembly includes a rotor bracket and a housing. The actuator is connected to the rotor bracket to cause the rotor bracket to rotate during actuator actuation. The actuator and the rotor bracket connected thereto are housed within the housing. The mounting bracket connects the physical appendage to the rotor bracket whereby the physical appendage moves between stowed and deployed positions during actuator actuation. The actuator is either an electric motor actuator or a pneumatic actuator that are substitutable with one another to assemble the assembly without modification to the common parts sub-assembly or the physical appendage. The physical appendage may be either a stop sign or a crossing guard arm that are substitutable with one another to assemble the assembly without modification to the common parts sub-assembly or the actuator.

Abstract: A sign assembly comprising includes a reflective panel, first and second sign panels, and a LED strip. The first and second sign panels sandwich the reflective panel. The first and second sign panels form a channel therebetween. The LED strip is positioned within the channel. The first and second sign panels may be identical and/or have letter embossments. The reflective panel may be white with the first and second sign panels being clear PMMA (Polymethyl methacrylate) panels.
