Leading lights are a pair of light beacons used in navigation to indicate a safe passage for vessels entering a shallow or dangerous channel. At night, the lights are a form of leading line that can be used for safe navigation. The beacons consist of two lights that are separated in distance and elevation, so that when they are aligned, with one above the other, they provide a bearing. Range lights are often illuminated day and night.

How to map

Note that lights must bear a sector number (# = 1, 2, 3, ...) even if there is only one sector.
