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:
“Baltimore lay very near the immense protein factory of Chesapeake Bay, and out of the bay it ate divinely. I well recall the time when prime hard crabs of the channel species, blue in color, at least eight inches in length along the shell, and with snow-white meat almost as firm as soap, were hawked in Hollins Street of Summer mornings at ten cents a dozen.”
—H.L. (Henry Lewis)
“The eastern light our spires touch at morning,
The light that slants upon our western doors at evening,
The twilight over stagnant pools at batflight,
Moon light and star light, owl and moth light,
Glow-worm glowlight on a grassblade.
O Light Invisible, we worship Thee!”
—T.S. (Thomas Stearns)
