For those who don't want to go all in on home automation, you can buy solar timers for your lights that have an on off button, but also accept your lat long as a parameter and contain a solar calendar internally; they will turn your lights on and off automatically around dawn and dusk (and variations of).
There are now even LED lightbulbs (~$7-10 each) that have light sensors in them that will run dusk-to-dawn. Is a lot better than trying to remember to switch the porch lights on/off every day! :)
