Where do green lights commonly appear in marking?

Green lights are commonly used in maritime navigation to indicate the starboard (right) side of a waterway or channel. When it comes to buoy markings, green lights are typically associated with horizontally-banded buoys. These buoys serve to guide mariners safely through navigable waters and are essential for determining the correct side of the channel during nighttime or low-visibility conditions.

This use of green is part of the standardized system for navigational markers, where the color coding plays a fundamental role in maritime safety. Horizontally-banded buoys, with a combination of green and white, clearly show their position and purpose to approaching vessels. This helps ensure that mariners can navigate safely and efficiently, especially in busy or narrow channels.

Other types of buoys, like vertically-striped or yellow buoys, do not typically feature green lights, as their color schemes and markings indicate different navigational information. For example, vertically-striped buoys usually signify navigational hazards or safe berthing areas, while yellow buoys represent caution areas or indicate special geographical features. Spherical buoys are often used for various purposes but do not typically feature green lights as part of their identification.
