New York: Syracuse – Upside-down traffic lights

When the city of Syracuse, New York started installing traffic lights in the 1920s the Irish community didn’t take kindly to the set of lights put up on a busy intersection on Tipperary Hill. They did not like the fact that the ‘red light’, which they associated with the British, was above the ‘green light’ – green being the colour of the Irish. So, some youths in the area threw stones, breaking the red lamp. The city replaced the lamp only for it to be smashed again. The city eventually gave up flipping the light so the green light was at the top. These upside-down lights remain until this day and have become a local attraction.
