On 11 May 2015, before the Life Ball and the Eurovision Song Contest in Vienna (Austria) the city changed some traffic lights to "", these are designs with homo- and heterosexual couples, hugging or holding hands. In June 2015, Salzburg (at Staatsbrücke) and Linz (at Mozartkreuzung) followed suit with the same designs. However, in December 2015 a city traffic minister of the party FPÖ dismounted the privately sponsored faceplates, deeming them unnecessary.
