Abstract: An apparatus and method for controlling light from a non-rectangular light source. The apparatus and method relate to using a light guide of a single piece of light-transmissive material having a plurality of external surfaces. One external surface is shaped to collect and substantially collimate light from the light source into the interior of the light guide. At least one external surface is shaped to internally control and direct light such that it issues from the light guide in a substantially rectangular pattern and with substantially total internal reflection. The light guide can be used to create a single controlled beam pattern. In another aspect, one light guide could be adapted to issue two controlled beam patterns. Still further, two light guides could be mounted in a common housing and used to generate two beam patterns. One exemplary application of two beam patterns is a bow light for marine vessels.

Abstract: The present invention includes a sound producing device assembly adapted for mounting a sound producing device assembly within a cavity. The sound producing device assembly is adapted for mounting within a cavity, such as a cavity within a boat. The assembly includes a sound producing device, a tubular member operatively connected to the sound producing device, and a flange operatively connected to the tubular member such that the flange connects to a surface.
