West was most famous for his role as the Caped Crusader when the classic “Batman” TV series aired in 1966. The pop culture icon died last Friday, aged 88, following a battle with leukemia.
The signal is a symbol of hope for characters in the comic book series who would shine the light to summon Batman’s help.
The actor reportedly failed to get major roles after playing the popular superhero, but later enjoyed success after being cast as the voice of the mayor of Quahog in the animated series, “Family Guy.”
