Lights, ancient refers to the ancient-lights doctrine, a common-law principle that allows a landowner to acquire an easement preventing a neighbor from building an obstruction that blocks light from passing through the landowner's window after 20 years of uninterrupted use. This window or opening is called an ancient light. The doctrine is rarely applied in the United States and has been repudiated. It means that a landowner has a legal right to a reasonable amount of light, free from interruption, over adjoining land.
