I just purchased a brand new outdoor light for my house. It is operated
by a normal switch like most lights.. However, my Wife is always
complaining that I don't remember to turn it off in the morning. So, to
avoid future nagging (aside from remembering to turn it off), is there
some sort of device which I can put in series with the light to detect
night and day?


Yes. Any hardware store should have them.
