ABSTRACT:
A portable warning device in the form of a stanchion which is to be readily movable and locatable at any desired location. The portable warning device includes a movable light assembly to attract attention to the warning device to any human being which passes nearby. Once the human being reaches within a certain number of feet in distance from the warning device, a prerecorded message is emitted to audibly warn the human being. Any unauthorized removal of the warning device will immediately activate an antitheft alarm which will produce some form of an audible signal calling attention to the fact that thievery of the device is occurring.
