Street light

A street light or street lamp, also well-known as a light standard or lamp standard, is a raised light on the edge of a road, turned on or lit at a convinced time every night. Modern lamps may also have light-sensitive photocells to turn them on at dusk and off at sunrise, or activate automatically in dark weather. It is also not uncommon for street lights to be on posts which have wires strung between them (telephone poles or electrical poles).
