Why are highway lights so high?

The street lights on the highway are so high. Why don’t they lower the height so that the light can be brighter?
  • Wider illumination area: High street lights can light up more area on the roads. In this way, they won’t leave any blind areas, and the light will be more uniform.
  • Brighter light: The higher the light, the brighter the light will be. Brigher lights can ensure the safety of vehicles.
  • Resisting the wind: Higher street lights can resist stronger wind, preventing accidents like tilting and collapse.
