turn LED on at dark/off during day

[stormin norman]

There has to be a 'simple' method on turning a LED on at night and off during the day, without me manually turning a switch on and off. Thinking a light sensitive eye to detect daylight...but after that...what do I need?

if you type - day - night sensor switch circuit into google, you will come up with lots of hits
for circuits
