Street lighting is lighting used to illuminate roads, sidewalks, or other public areas at night or in low light conditions. Its primary purpose is to improve safety for road users and to make it easier to navigate around the area. Street lighting is typically mounted on poles or tall structures, and often uses lighting technologies such as incandescent bulbs, solar panels, fluorescent bulbs, or more energy-efficient semiconductors (LEDs).

Some commonly desired features in modern street lighting include adjustable brightness, motion sensors to save energy by turning on lights only when needed, and the ability to be controlled remotely via a smart connected street lighting management system. Current technology also includes the use of LED lights, which are more energy efficient and have a longer lifespan than conventional lighting technology. This helps reduce the operating costs and environmental impact of street lighting systems.
