Disclosed herein are embodiments of a portable sign for removable disposition about a traffic control device, and methods of making and using such a portable sign, whereby the portable sign includes a sleeve having sleeve outer and inner surfaces, the sleeve inner surface defining a sleeve opening configured to removably receive the traffic control device; a panel coupled to the sleeve in overlaying engagement; and an information-conveying indicium coupled to the panel, for example an information-conveying indicium associated with the traffic control device.

A device includes a cone having a cone first end with a flange, the cone extending to a cone second end. A base has a recess to mate with the flange of the cone. The base also has multiple base openings. A ring is shaped to fit on top of the flange and has multiple ring openings to mate with the base openings in a top of the base for releasably coupling the cone to the base.

Visual warning devices that include illuminated rectilinear arachnid structures that break inattentional blindness of observers. The illuminated rectilinear arachnid structures can be mounted on height-adjustable support posts that extend upright from bases. Alternatively the illuminated rectilinear arachnid structures can be provided with magnets to mount the visual warning devices to metal structures. The illuminated rectilinear arachnid structures include pairs of arms that radiate outward from a central head. The arms and central head can be made from a translucent material through which light can be transmitted to illuminate these structures. Lights for illumination can be provided in the heads. The length of the arms can be adjustable, and the arms can be retracted and/or folded into a storage configuration.

A lighted temporary barrier having a body of at least one length of hollow translucent tubing, a string of LEDs with a power source, and connectors on each end for coupling to a structure such as a traffic cone or traffic tube so as to provide a solid barrier between the two structures. The body may be made of at least a first length of translucent tubing forming a body and an optional second length of translucent tubing fitting within the first length of translucent tubing to form an extendible body. Alternatively, the body is made from a plurality of telescoping tubes, in one or both ends. The LED strand may be secured within the body or to the outside of the body.

A retaining member is described. The retaining member forms part of a stanchion of a barrier assembly. The retaining member includes an undulating open channel extending completely through the retaining member. The channel is adapted, in use, to retain a flexible elongate member (e.g., a rope or cord) and to restrain movement of the flexible elongate member relative to the retaining member.

A safety cone enhancer fits onto a traffic cone or safety cone. The traffic cone or safety cone has a conical member with a first diameter at a base of the conical member and a second diameter at a top of the conical member. The safety cone enhancer has a round or polygonal member with a hole therethrough, the hole having a diameter which is less than the first diameter of the traffic cone and greater than the second diameter of the traffic cone. The safety cone enhancer has a plurality of arms extending from the round or polygonal member; and at least one of: a first hole in said round or polygonal member extending through said polygonal member from the top surface to the bottom surface, said first hole being configured to receive a first signaling device; and a second signaling device which shines light from a surface of the round or polygonal member.
