Abstract: A horn device includes a trumpet fixture which removably attaches to the valve portion of a canister containing a charge of compressed air. An actuator button on the trumpet fixture is operable to open the valve assembly of the canister causing release of the pressurized air through the trumpet fixture to produce a loud horn noise. One or more light signal lamps are provided on the trumpet fixture. In a preferred embodiment, the light signal lamps are powered by one or more batteries carried on the trumpet fixture. In a further embodiment, a light emitting lamp on the rear facing end of the trumpet fixture is covered with a split color lens, having a green half and a red half to provide auxiliary running lights of a water vessel. In still a further embodiment, the light emitting lamp is provided in a light signaling device which is hingedly attached to the trumpet fixture. Control buttons allow selective activation of the light signal lamps in one or more modes of operation (e.g.
