Maybe when you are inside the lighthouse and look outside the window, when your flashlight turns on there will be a shadow or sth, and when it turns off and then turn on again, it disappears. I remember there is some research about the art of horror games or its style on how to trigger the fear of players on the internet that you can read to apply in your game.
