What is a flashing green light buoy?

A flashing green light buoy is a navigational aid used in maritime environments to mark specific locations, such as channels or hazards. The buoy emits a green flashing light to help guide vessels safely, particularly during nighttime or low visibility conditions. These buoys usually indicate the right side of a channel when approaching from the sea, adhering to the IALA buoyage system. Their distinctive color and light pattern help mariners identify safe passage routes.
