The simplest way is exactly the circuit you have, except that when the door is fully closed, it will be off and when it is fully open it will be off. You have to come up with some track a wire can ride on or some piece of metal on top of the door that will make contact when opening, but not when shut or fully open.

I don't know, that is my idea on the simple way to do it.

That is kind of strange we replied to a 5 day old thread at the same time...
