The Paulding Light (also called the Lights of Paulding or the Dog Meadow Light) is a light that appears in a valley outside Paulding, Michigan. Reports of the light have appeared since the 1960s, with popular folklore providing such explanations as ghosts, geologic activity, or swamp gas. In 2010, Michigan Tech students conducting a scientific investigation of the light were able to see automobile headlights and tail lights when viewing the light through a telescope. They recreated the effect of the light by driving a car through a specific stretch of US Highway 45 (US 45).
