In the late 1800s, gas street lamps were commonly used to light up the streets. These lamps featured a tall pole made of cast iron, The lamp used a gas flame, which was lit manually every evening and extinguished at dawn. As electricity became more widespread in the late 19th century, gas street lamps were gradually replaced by electric streetlights. One of the earliest examples of this was the "Brush Light," invented by Charles F. Brush in 1876. Thomas Edison's incandescent light bulb was introduced in the late 1870s, and by the 1890s, electric street lights using Edison's bulb were becoming more common. This design was inspired by an original Edison street post out of New Orleans.
