That's a pre-release image, right? Neat. Looks like they originally intended rats to stay out of brightly lit areas, but I don't think that behaviour made it into the game.

Regardless, all those little lights you see in the game are ratlights. If you play through the levels and pay attention to them, plenty of them are on the floor, infront of holes, and so on. Also, it stands to reason the Boyles made their fortune with a "consumer product" that everyone needs, not floodlights that don't appear all too often.
