From Pop-Up Flashing Cones comes a uniquely designed traffic cone that can be seen from greater distances than flares. Fabricated of a durable composite, the 28-inch reusable cones collapse into a 21/2-inch deep, 1-foot-square base, making for easy storage. Four cones can be stacked into a soft, handled bag measuring one cubic foot for convenient trunk storage. Marked with two types of reflective tape, the cones can also be equipped with a battery-powered steady or flashing light.
