Abstract
A safety marker apparatus comprising a hollow body including at least four vertex elements interconnected by flexible resilient rods, the body being adapted to be compressed into a stowed state upon application of an external force and expanded into a deployed state, the flexible resilient rods forcing the hollow body to adopt the deployed state in an absence of the external force. In one embodiment, an illumination sub-system is provided in at least one vertex element.
