How do streetlights know to turn themselves off? Each one has a timer?

I've only guessed it before, but then I've observed streetlights turning themselves on when clouds are heavy during daytime, and turning off briefly when lightning flashes overhead :p Jaime L. Garcia 2014-01-02 00:00:04 This reminds me of that elusive one-quest-per-d ay in WoW where a wizard would ask you to switch on the lights of Dalaran at around 6pm game time.

All the while I thought it was the barangay tanod or something who did all the switching on and off! :) Josiah Tendero Habana 2014-01-03 00:00:06 Roy Tang diba pinakita ko yung sa kanto namin na pag may dumaang tao, namamatay Danniel Paxi Alcantara 2014-01-03 00:00:07 Hala!
