Lighthouse and ships in the night. Original shot was taken in Northern Ireland, at the Haulbowline lighthouse. Haulbowline is a main sea light and also serves to guide vessels from seaward through the entrance channel into Carlingford Lough. It is built on a wave-washed rock, exposed only at low tide. It is located in the middle of the entrance to Carlingford Lough, just on the northern side of the border between Ireland and Northern Ireland. Accessible only by boat.
