The frequency of the electricity causes a flicker effect 50Hertz you notice it more on street lighting because of the greater amount of surrounding darkness.In a building with rotating/high speed machinery by law lights have to be fitted with a diffuser to eliminate this as it can cause machinery to look stationery.

They don't shimmer. The ground retains heat longer than the air and it is the rising heat that makes it look like the lights are shimmering!

Its something to do with the light wave patterns crossing the darkness, something like that....its sulphur light inside thats why its yellow/orange and gives a glow effect

yep jamesc is right...i work in a factory and if one of our tube lights is flickering it has to be changed as it can give a "strobe effect" and cause u to lose ur hand. street lighting aint so important
