It repeatedly happens that we often forget to turn the lights off or have to search for the switches in dark. So, it becomes apparently needed to design apparatus that could show the on-and-off condition of the light and operate. We could use remote control to either turn the light on or off. At night, we could choose the light-needing rooms and have the signs shown on the remote control. When we leave the room, we could get to know the condition of the light through its screen and could also turn the light off through the screen.
