Hello everyone!
Merry Christmas firstly. This is a simple automatic redstone lamp, which turns on when the sun goes down, and turns off when the sun rises, without you do anything. This map is meanless, it just shows how it works. You should try it in survival mode, to make your house more comfortable! :)
