Every night at 8:30, the city of Providence, RI, blinks its lights for the patients at Hasbro Children’s Hospital. The Good Night Lights tradition began with local cartoonist Steve Brosnihan using his bike light to say ‘goodnight’ to a young patient from a nearby bus stop. Other residents, hotels, and passing tugboats soon started to join in, and the children have come to love the nightly ritual so much, they signal back with their own lights as a thank you.
