Beacon

A beacon is an intentionally conspicuous device designed to attract attention to a specific location.

Beacons can also be combined with semaphoric or other indicators to provide important information, such as the status of an airport, by the colour and rotational pattern of its airport beacon, or of pending weather as indicated on a weather beacon mounted at the top of a tall building or similar site. When used in such fashion, beacons can be considered a form of optical telegraphy.

Famous quotes containing the word beacon:

    It was a remarkable kind of light to steer for,—daylight seen through a vista in the forest,—but visible as far as an ordinary beacon at night.
    Henry David Thoreau (1817–1862)

    Hm, the beacon of the press. In the hell to which all journalists must descend when they die, Mr. Wiggam, we shall sit at red hot desks with quills of fire in our hand and spend eternity on eternity writing about the salubrious weather of that region. Let us serve our apprenticeship here thoroughly and intelligently.
    Ben Hecht (1893–1964)

    It illumineth the face, which as a beacon gives warning to all the rest of this little kingdom, man, to arm ... this valor comes of sherris.
    William Shakespeare (1564–1616)
