Abstract
A portable hazard-warning light assembly (10) that is designed to warn on-coming vehicular traffic of a hazardous traffic/road condition. The assembly (10) consists of an elongated tubular body (12) having attached to its top edge (12A) a removable lens head (18) that houses an incandescent light bulb (62) that may be connected to a flasher (36). The bulb and flasher are powered by a single battery (60) that is housed within a battery compartment (20) located at the bottom edge (12D) of the body (12) and that includes a threaded battery compartment cover (28). The body (12) also has attached a slidable leg ring (34A) that has pivotally attached four retractable legs (34D) that are each supported by a leg brace (34H). To extend the legs, the ring (34A) is grasped and lowered. Conversely, to retract the legs, the ring is moved to its upward position. To apply power to the light bulb (62), the cover (28) is rotated which allows the battery (60) to move upwards and complete the electrical power circuit.
