Abstract: A combination marine horn and bow light is provided. According to the invention, a single unit houses a bow light assembly affixed to a housing which contains a sound emitting portion of the horn. The bow light and sound emitting portion of the horn are preferably mounted on the top surface of a boat bow deck. The horn is installed below the bow deck surface. The entire unit is powered by a single electrical supply. Alternatively, separate bow light and horn units may be affixed to the deck or hull sidewalls. In this embodiment, each bow light would have a separate colored lens cover. In a further embodiment, for either deck or sidewall mounting, the light and horn combination, including the sound emitting and sound producing portions, are all mounted on the exterior of the vessel.

Abstract: An articulated light head for navigational lights on motor boats. The light head incorporates a movable stem plate within an articulator base for manual positioning of the navigational light with respect to its supporting conventional hull pole as attached to the hull of the boat. The movable stem plate is frictionally secured between a stem plate trapper and the articulator base. A light base is fitted on top of the articulator base enclosing both the movable stem plate and stem plate trapper within the light head. A navigation light is supported by the light base and powered by electrical current directed through the light head. The navigation light is protected by a dome which fits over the light base.
