An all-round marine navigation light which generally limits the direction of light transmission to a selected angle above and a selected angle below a plane in which light transmission is to be generally directed. The navigation light generally includes a base defining a light limiting perimeter wall, a circumferential lens which allows light transmission in all directions of the selected plane, the lens being secured to the base, a cap defining a downwardly projecting light limiting perimeter wall, the cap being secured to the lens, and the upwardly and downwardly projecting perimeter walls blocking light transmission through lower and upper portions of the circumferential lens, respectively, to generally limit the direction of light transmission to a relatively narrow band generally within and/or adjacent to a selected plane. Also disclosed is an all-round marine navigation light having a light assembly, a connector configured for attachment to a pole, and the light assembly being attached to the connector through an articulated joint, whereby the orientation of the marine navigation light can be adjusted with respect to the connector to facilitate mounting of the light to a variety of sloped surfaces while generally limiting the direction of light transmission to a relatively narrow band generally within and/or adjacent to a selected plane.
