You should know better than to post a pic and only expect comments about YOUR question! :lol:
And if I hadn't asked, I would have missed the planks below and closer to the house, and now see the ladders as shelves. Thanks! I just knew there had to be something I was missing.
As for the light, I think you are already served by the central location, unless you need something switched at the door, and that isn't able. If you are doing a covered porch, then I'd go with a light inside of that, instead of on the house wall.
