Abstract
An emergency warning device comprising a base, three arms extending upwardly from the base to define an equilateral triangle, one of the arms extending horizontally on the base and the other two arms extending upwardly. Each arm has reflective and fluorescent portions on opposed surfaces thereof. The fluorescent portions of said arms comprising spaced walls and each wall has at least one opening therethrough. The opening in one wall is staggered with respect to the opening in the other wall such that portions of one wall overlie the opening in the other wall and such that air striking the device flows in a sinuous path through the device reducing the drag on the device.
