The reddish and yellow layered towers in the sand dunes at the west coast of the peninsula Walcheren, Zeeland, The Netherlands, aren't lighthouses, but are the so called 'leading lights' or 'range lights'. The difference in height of these towers is essential, because they both are radiating a beam of light. Vessels at sea can maneuver this way that the beams are aligned in the same horizontal position, so providing a bearing for vessels in order to achieve a safe passage in entering a shallow or dangerous channel like this one.
