Why do street lights flicker at night?

The street light near my house keeps flickering, which is very annoying. What is the reason? How can we fix it?
  • Voltage fluctuation: The voltage of the power supply controls the brightness of the light. If it keeps fluctuating, the brightness will be unstable, making the light flicker.
  • Aging lights: After the light works for a long time, it will age. The aging or worn lights may flicker.
  • Influence of the weather: Sometimes the wind is strong, causing poor contact between the lights, so they will flicker.
