You leave the light (switch) on, then plug the light into the timer which turns the electricity on and off to the light.
This works great for small lights like I have, but if you are using VHO, PC or MH you will want to be sure to check the rating for the timer!!! The cheap ones we have been discussing are made to turn an ordinary table lamp or such on/off.
