From London's Trafalgar Square to New York's famed Empire State Building, more than 10,000 buildings will be cast in blue light to honor those who struggle with autism.
In Cleveland, Ohio, the Terminal Tower will join CenturyLink Field, the Great Pyramid in Egypt, the Las Vegas "welcome" sign and One World Trade Center.
Here's Brooklyn Nets player Deron Williams and family flipping the switch to turn the Empire State Building blue.
Find a building in your area that's "Lighting It Up Blue" by visiting Autism Speaks and entering your zip code in its search tool. Other buildings that will light up the sky in sapphire light for autism include the Prince's Palace of Monaco, the Nelson Mandela Bridge in South Africa and the Ministry of Education in Kiev, Ukraine.
How do they do it? Turns out Home Depot and Philips teamed up to create a special "autism blue" light bulb to turn any home or building into a beacon of autism awareness called the Autism Speaks 25-Watt Incandescent A19 Transparent Blue Light Bulb. It's just $3, and there's still time to swap out your porch light before nightfall.
