Whilst I deal with much smaller and faster aircraft than the 737, I'd imagine there'd be numerous microswitches or similar around the door frame, which once released would send an illumination signal to the lighting controller or similar computer.
Although if the theory of the door not being installed correctly holds true, then I guess I'm way off the ball with that theory.
