beacon light
Tower's warning lamp
A beacon light is a bright, often rotating or flashing light positioned to serve as a signal or guide, typically warning of hazards or marking locations for navigation.
Lighthouses use beacon lights to alert ships to dangerous coastlines, while airports employ them to help pilots identify runways.
The term also applies to emergency vehicle lights and warning beacons atop tall structures.
The beacon light swept across the fog, guiding the vessel safely into harbor.
