Art,I like a lot of lights and think it makes the layout look very nice when running at night time. So I add a lot of lighting that people who like to run only day light don't really need.
So areas that I have lights are, In the work house and around the silos and in the elevator and the unloading facility. If no work house then at the top of each silo so that the manhole area is lighted. Also on the Grain trucks themselfs. Lighting at the doorways and access ladders.
I think that the lights up on the silos themselfs really add dimension to them when the room lights are down a bit. Art Itried to get the pictures big enough so that you could see the little light fixtures.
