US Patent 7942544 Hose mounted visual indicating device

A visual indicating device for mounting on a hose includes a body having an outer wall and defining a central passage extending axially through the body between a first end and a second end, and a plurality of lights arranged around the annular body so as to be visible from beyond the outer wall. A power source is arranged within the annular body, and a switch selectively energizes the plurality of lights from the power source. The visual indicating device includes groups of differing colored lights. Mounted on a hose, one of the groups indicates the general direction of the nozzle and another of the groups indicates the general direction of an exit. The switch automatically energizes the lights upon pressurization of the hose.
