After the [[September 11 attacks]], several people independently conceived the idea of using lights for remembrance. These efforts were merged under the umbrella of the [[Municipal Art Society]] and [[Creative Time]].<ref>{{cite web |url=http://mas.org/programs/tributeinlight/ |title=Tribute In Light – The Municipal Art Society of New York |archive-url=https://web.archive.org/web/20100825172813/http://mas.org/programs/tributeinlight/ |archive-date=August 25, 2010 |url-status=dead |access-date=November 4, 2014}}</ref>

''Tribute in Light'' began construction on March 11, 2002, and initially ran as a temporary installation from March 11 to April 14, 2002, and it ran again on September 11, 2003, to mark the second anniversary of the attack.<ref name="auto"/> Since then, it has been repeated every year on September 11. It was announced that 2008 would be its final year,<ref name="godark" /> but the tribute was continued in 2009.<ref>{{cite news |publisher=NY1.com |title=September 11th Tribute Lights Up Again |url=http://ny1.com/content/top_stories/105290/september-11th-tribute-lights-up-again/Default.aspx" |url-status=dead |archive-url=https://web.archive.org/web/20090914135857/http://ny1.com/content/top_stories/105290/september-11th-tribute-lights-up-again/Default.aspx |archive-date=September 14, 2009 |df=mdy-all}}</ref>

On December 17, 2009, it was confirmed that the tribute would continue through the tenth anniversary of the attacks in 2011.<ref>{{cite news |url=http://cityroom.blogs.nytimes.com/2010/09/10/tribute-in-light-will-keep-shining-this-year-and-the-next// |newspaper=New York Times |title='Tribute in Light' Will Keep Shining, This Year and the Next |date=September 10, 2010 |first=David W. |last=Dunlap |access-date=September 11, 2010 |archive-date=July 26, 2011 |archive-url=https://web.archive.org/web/20110726232605/http://cityroom.blogs.nytimes.com/2010/09/10/tribute-in-light-will-keep-shining-this-year-and-the-next/ |url-status=live }}</ref> In 2012, plans were underway for the [[National September 11 Memorial & Museum]] to assume the lease for the MTA property used during this tribute, and to begin transitioning operation of the tribute from the Municipal Art Society to the memorial foundation.<ref>{{cite web |last=Mann |first=Ted |title='Tribute' Handover |url=https://www.wsj.com/articles/SB10000872396390443437504577545520666491842 |work=The Wall Street Journal |date=July 23, 2012 |access-date=July 24, 2012 |archive-date=March 3, 2016 |archive-url=https://web.archive.org/web/20160303121742/http://www.wsj.com/articles/SB10000872396390443437504577545520666491842 |url-status=live }}</ref>

The lights are produced by an American company named Space Cannon,<ref>{{Cite web |url=http://www.spacecannonsne.it/ |title=Home - Spacecannon SNe - Excellence in the lighting field |website=spacecannon SNe |language=en-US |access-date=2019-05-05 |archive-date=May 6, 2019 |archive-url=https://web.archive.org/web/20190506225826/http://www.spacecannonsne.it/ |url-status=live }}</ref> which sends a team every year to help with the installation.<ref name=":1" /> A [[Las Vegas]]-based company, Light America, was also part of the team who implemented the project.<ref>{{Cite web |url=https://www.lasvegasnow.com/news/world-trade-center-memorial-has-local-connection/79318001 |title=World Trade Center Memorial Has Local Connection |date=2002-03-12 |website=LASVEGASNOW |language=en-US |access-date=2019-01-27}}</ref>

Each year, about 30 technicians, electricians, and stagehands work for about ten days to install the lights. During a testing phase of several days, observers in Brooklyn, Staten Island, New Jersey, and uptown Manhattan help make sure that the beams are adjusted accurately.<ref name=":1" />

The project was originally going to be named ''Towers of Light'', but the victims' families felt that the name emphasized the buildings destroyed instead of the people killed.<ref>{{cite news |url=http://news.bbc.co.uk/2/hi/americas/1857699.stm |title=Tribute in light to New York victims |access-date=April 27, 2008 |work=BBC News |date=March 6, 2002 |archive-date=January 29, 2012 |archive-url=https://web.archive.org/web/20120129170013/http://news.bbc.co.uk/2/hi/americas/1857699.stm |url-status=live }}</ref>

A permanent fixture of the ''Tribute in Light'' was at one point intended to be installed on the roof of [[One World Trade Center]],<ref>{{cite web |title=Freedom Tower rendering Time-lapse |url=http://www.wtc.com/media/videos |publisher=Silverstein Properties Inc. |access-date=March 22, 2015 |archive-date=February 20, 2015 |archive-url=https://web.archive.org/web/20150220192633/http://www.wtc.com/media/videos/ |url-status=live }}</ref><ref>{{cite web |title=SOM Freedom Tower Fact Sheet |url=http://www.renewnyc.com/content/pdfs/freedom_tower_fact_sheet.pdf |archive-url=https://web.archive.org/web/20051103104549/http://www.renewnyc.com/content/pdfs/freedom_tower_fact_sheet.pdf |archive-date=2005-11-03 |url-status=live |publisher=Lower Manhattan Development Corporation |access-date=March 22, 2015}}</ref> but it was not included in the finished design.<ref>{{cite web |title=Design changes to base, spire of 1 World Trade Center |url=http://www.myfoxny.com/story/19229185/new-renderings-of-1-wtc-show-design-changes |publisher=Fox New York |access-date=March 22, 2015 |url-status=dead |archive-url=https://web.archive.org/web/20150317171748/http://www.myfoxny.com/story/19229185/new-renderings-of-1-wtc-show-design-changes |archive-date=March 17, 2015 |df=mdy-all}}</ref>

Since 2008, the generators that power ''Tribute in Light'' have been fueled with biodiesel made from used cooking oil collected from local restaurants.<ref>{{cite web |last1=Bevill |first1=Kris |title=Tri-State Biodiesel fuels Sept. 11 memorial |url=http://www.biodieselmagazine.com/articles/2726/tri-state-biodiesel-fuels-sept.-11-memorial/ |publisher=Biodiesel Magazine |access-date=September 12, 2017 |date=September 15, 2008 |archive-date=September 13, 2017 |archive-url=https://web.archive.org/web/20170913043926/http://www.biodieselmagazine.com/articles/2726/tri-state-biodiesel-fuels-sept.-11-memorial/ |url-status=live }}</ref>
