You can see that when it starts becoming dark in the evening streetlights are ON yellow light is.

  • Yellow light is proved to have better transmission than a white or cool street light
  • An advantage for late night drivers. (fog doesn't make the light less bright).  
  • Yellow light is because of the usage of sodium lamps in streetlights.  
  • These sodium lamps use least of electricity to produce more amount of light.
