Though the Empire State Building is famous for its height, it is also known for something else—its Tower Lights. The building's
top 14 floors are actually a 200-foot tower, complete with lights capable of producing an array of colors. Beginning with a single searchlight beacon in November 1932, which announced that Franklin Roosevelt had become president, the lights have changed much over the years. Now, several hundred fluorescent tubes make much more possible. With the flip of a switch, the tower's white lights can be changed to honor special people and events. For example, in 1976, the Tower Lights were changed to red, white, and blue; this was to honor the country's bicentennial. When the Yankees won the 1977 World Series, blue and white lights flashed. On September 24, 2009, red lights were used to mark the 70th anniversary of The Wizard of Oz. The lights glowed green on Earth Day 2010. Over the years, the Empire State Building has had countless visitors. Prince Charles, the King of Siam, schoolchildren, tourists, and many others have come to New York City to admire it. However, for many people, the simple act of changing the lights inspires just as much awe as the building's soaring height and stunning views. Notes 1.
