Street Light

A street light, lamppost, street lamp, light standard, or lamp standard is a raised source of light on the edge of a road or walkway, which is turned on or lit at a certain time every night. Modern lamps may also have light-sensitive photocells to turn them on at dusk, off at dawn, or activate automatically in dark weather. In older lighting this function would have been performed with the aid of a solar dial. It is not uncommon for street lights to be on posts which have wires strung between them, such as on telephone poles or utility poles.

Famous quotes containing the words street and/or light:

    Anger becomes limiting, restricting. You can’t see through it. While anger is there, look at that, too. But after a while, you have to look at something else.
    Thylias Moss, African American poet. As quoted in the Wall Street Journal (May 12, 1994)

    For eighteen hundred years, though perchance I have no right to say it, the New Testament has been written; yet where is the legislator who has wisdom and practical talent enough to avail himself of the light which it sheds on the science of legislation?
    Henry David Thoreau (1817–1862)
