- Sector_light abstract "A sector light is a man-made pilotage and position fixing aid that consists of strictly de-limited horizontal angle light beams to guide water-borne traffic through a safe channel at night in reasonable visibility. Sector lights are most often used for safe passage through shallow or dangerous waters. This may be when leaving or entering harbour. Nautical charts (paper and electronic) give all the required information.Sectors of colored glass (or plastic) are placed in the lanterns of these lights. The light will then show these colors when observed certain bearings. Bearings referring to a sector are given in degrees true as observed from sea. Though the colors of the light will change, the characteristics will not. The change of color is not abrupt. The transition is made through an arc of uncertainty of 2° or greater.The colors that are used, are conform to the IALA Maritime Bouyage system that is designed by the International Association of Lighthouse Authorities: white - this sector is in the middle of the safe channel red - indicates the port edge of the channel for vessels approaching the light source green - indicates the starboard edge of the channel for vessels approaching the light source.A ship that is sailing in safe water and then sees the red (or green) color of the light has to make an alteration in course.The world has different navigation stereotypes managed by IALA (International Association of Lighthouse Authorities). For example, the United States uses a signalling stereotype which is the opposite of Europe. In USA, the red light indicates the starboard side of the channel for harbour bound vessels, while the green light indicates the port side of the same channel. An expression to remind of this is \"red right returning\".".
