You are more likely to notice a street light turn off next to you rather than notice a street light turn off far away from you. Street lights turn on and off rather often, so this is a case of confirmation bias. This is compounded by the fact that many street lights use high pressure sodium type light bulbs, which tend to "cycle" when failing

In order to achieve this goal, a single control unit is needed for each lamp. In this way the system can individually control the street light depending on the brightness of the environment by means of light sensors, motion sensors and a smart control system.
The ballast (or transformer) reduces the voltage and regulates the electric current to produce a steady light output. The capacitor is used to stabilize voltage and power flow. Compared to traditional lamps, smart street lamps have the capability to be remotely powered on, off or dimmed by means of controllers.
A street lamp is made out of a lamp socket which mechanically supports electrical connections and allows the lamp to be conveniently replaced. The ignitor provides the high-striking voltage needed to ignite a streetlamp. The ballast (or transformer) reduces the voltage and regulates the electric current to produce a steady light output.
The main purpose of intelligent street lighting is to better light up the roads, pavements and parking spaces to guarantee citizens' security. To ensure visual safety to drivers and pedestrians, smart lighting needs to meet specific values of luminance, illuminance or dimness, uniformity, and glare according to the road type.
They took the place of human intervention, functioning as an automation for switching the light on and off. Since then, street lighting needed to become more effective, less energy consuming, and less polluting. So, control systems have evolved to become 'smart' by allowing lamp control and data collection.
