Toggle Relay

Hi im new here and have been doing a lot of reading i couldnt find exactly what i need for my application. what i want to do is have a relay connected that will trigger an led to light up only when the relay receives power from to separate 12v sources. i know i can do it for one but for my application i need the relay to trigger only when both 12v soruces are live. can anyone help?

thanks that is what i was looking for, just to get this clear, i can use either of the three methods u mentioned above right?
