The Citgo sign that is located behind the Green Monster in Fenway Park caught fire on October 15, 2008.  Immediately "neon" was the blame.  Unfortunately the neon sign that was in the stadium since 1940 was rebuilt with LED's in 2005.  So in reality it was an LED fire, not a neon fire.  Why is it that neon is the scapegoat for all things that go wrong?  Just because LED's are a newer technology, doesn't mean it is a better technology.  Neon has stood the test of time, meanwhile LED's are still unproven.  And yes LED's can cause fires as well!
