A spiral configured structure formed of metal or polymer is naturally biased into an erected and spiral arranged position, to form either a cone, a cylindrical structure, or other shaped structure, and which includes a series of lights, or a highly illuminated or phosphorescence dyed cloth, to act as a warning structure to the surrounding environment. The spiral structures can be contracted, into a flattened or near flattened configuration, and held by a fastening band, into closure. Various cross bracings or members are applied, at particular locations of the spiral structure, to provide it with reinforcement and rigidity at their upper and lower regions.
