Lamp timers can be useful in a variety of circumstances. You can use a lamp timer for an added security measure by setting the timer to turn the lamp on when the house is vacant and make it seem like someone is home. You can also use a lamp timer to make lights turn on when you wake up, to make lights turn on when it begins to get dark outside, etc.
Plug the lamp timer into an electrical socket, then plug the lamp into the timer.
Turn the lamp on.
Set the dial on the timer to the correct time.
Set the timer for the times you want the lamp to turn on and when you want the lamp to turn off. There are two kinds of lamp timers: those with push buttons and those with red and green pins.
For timers with push buttons, push in the buttons that correspond with the times that you want the lamp to be on. Make sure that the buttons that correspond with the time that you want the lamp to be off are not pushed in.
For timers with red and green pins, set the time that you would like the lamp to turn on by inserting one of the green pins into the corresponding spot. Set the time that you would like the lamp to turn off by inserting a red pin in the corresponding spot
