A tv trailer for a new production of Jamaica Inn made me think of the typical film depiction of wreckers luring ships on to rocks using lights. Do any of the Mudcat seadogs have a view on this? It seems to me that since lighthouses and lightships warn you to keep away from dangers, seeing a light onshore would make a ship veer away rather than sail in to its doom. Putting lights OUT would more likely to confuse the navigator.
