Ce qu\u2019on appelait alors des fl\u00e8ches de direction sont apparues en Europe sous la forme de fl\u00e8ches qui se dressaient m\u00e9caniquement \u00e0 gauche ou \u00e0 droite. L\u2019\u00e9lectrification de l\u2019ensemble suivra. Les feux clignotants eux, semblent \u00eatre l\u2019invention de Percy Douglas-Hamilton. Un Am\u00e9ricain qui d\u00e9pose un brevet en 1907 \u00e0 propos d\u2019un signal lumineux de chaque c\u00f4t\u00e9 du v\u00e9hicule. Pour autant, les constructeurs ne consid\u00e8rent l\u2019int\u00e9r\u00eat des clignotants qu\u2019\u00e0 la fin des ann\u00e9es 30. L\u2019Histoire retient ainsi que c\u2019est en 1938 que les Buick sont \u00e9quip\u00e9es de s\u00e9rie de \u00ab <em>flash-way directional signal<\/em> \u00bb. Et encore, uniquement \u00e0 l\u2019arri\u00e8re.<\/p>\n<h2>Un son binaire<\/h2>\n<p style=\"text-align: justify;\">De mani\u00e8re simple, consid\u00e9rons le clignotant comme une ampoule \u00e9lectrique. Allum\u00e9e, puis \u00e9teinte, puis rallum\u00e9e, puis \u00e9teinte \u00e0 nouveau\u2026 Cette intermittence du courant \u00e9lectrique vient du bilame. Un syst\u00e8me jouant sur la dilatation des m\u00e9taux sous l\u2019effet de la chaleur (effet joule fournit par le courant \u00e9lectrique). Quand le m\u00e9tal est chauff\u00e9, il se dilate, le circuit \u00e9lectrique n\u2019est plus aliment\u00e9 et l\u2019ampoule s\u2019\u00e9teint. Quand il ne l\u2019est plus, il se contracte \u00e0 nouveau, referme le circuit et rallume l\u2019ampoule. C\u2019est ce changement d\u2019\u00e9tat qui g\u00e9n\u00e8re un petit bruit. Un<em> tic<\/em>, un <em>tac<\/em>, un<em> clic<\/em>, un <em>clac<\/em>, c\u2019est selon. Mais \u00e7a c\u2019\u00e9tait avant ! <\/p>\n<h2>Et de nos jours ?<\/h2>\n<p style=\"text-align: justify;\">Le syst\u00e8me bilame a fonctionn\u00e9 des ann\u00e9es 40 jusqu\u2019\u00e0 la fin des ann\u00e9es 60. Petit \u00e0 petit, des syst\u00e8mes \u00e9lectroniques ont remplac\u00e9 le bilame, des LED \u00e0 compter des ann\u00e9es 80. L&#8217;avenir s&#8217;\u00e9crit <a href=\"https:\/\/www.autosphere.fr\/blog\/media\/technologie\/les-feux-oled-draudi-dansent-dans-la-nuit\/2620\/\">en OLED<\/a>. Le hic, c\u2019est le silence de ces syst\u00e8mes. Du coup, leur absence donne l\u2019impression d\u2019un dysfonctionnement. Ainsi, il a \u00e9t\u00e9 ajout\u00e9 un syst\u00e8me avec un petit haut-parleur simulant le bruit du bilame d\u2019antan. C\u2019est ce bruit l\u00e0 que vous entendez aujourd\u2019hui dans votre voiture lorsque vous tournez \u00e0 droite, \u00e0 gauche ou mettez les feux de d\u00e9tresse.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Parfois discr\u00e8te, parfois envahissante, la commande des clignotants est accompagn\u00e9e par une sonorit\u00e9 devant confirmer son bon fonctionnement.
