Seaman Riley Hatcher covers a light on top of a buoy in order to activate it aboard USCGC Sycamore (WLB-209) in Long Island Sound, NY, on Oct. 20, 2021. In order to test the lights for functionality, Hatcher must place a bag over the light to simulate it being dark enough out for the light to turn on.
