Made by leaning my phone on car's window, while the car was stationary near a local backroad. Night was almost pitch black, phone picked up some sky light from nearby village or main road. One car has passed just in time to make a trail and light up the surroundings.
Photo itself isn't anything beautiful, but at that time it felt like something special.
