Before the creation of the seaside resorts of the Côte Fleurie (Flowery Coast) on the coast of the English Channel, fixed lights called tidal lights arranged along the shore signaled the coast to navigators. In the middle of the 19th century, the development of the port area of Trouville-Deauville required the installation of traffic lights adapted to the new infrastructures. Two fixed lights (one red and one green) were thus installed by ministerial decision of January 26, 1874, at the end of the two wooden piers intended to prevent the silting up of the channel at the mouth of the Touques. The red light (photo) is located on the east boom of the port channel.
