Abstract
A marine navigational light fixture includes a light source and a cutoff sub-housing holding the light source. The cutoff sub-housing has a main frame having first and second laterally opposite sides; first and second sidewalls projecting from the first and second sides of the main frame, respectively; and first and second cutoff surfaces located on the first and second sidewalls, respectively. The first and second cutoff surfaces are configured to provide practical cutoff of light emitted from the light source outside of a specified arc of visibility. The marine navigational light fixture also includes a main housing holding the cutoff sub-housing. A luminaire subassembly for the marine navigational light fixture includes a colored component having a color that is in the same color family as a color of light emitted from the luminaire subassembly. The colored component can be a lens, a filter cap, a PCB, and/or a telltale.
