The Bat-Signal is usually reserved for times of trouble, a call for the Caped Crusader to come out of the Batcave and defeat the villains.
But if you look up to the sky tonight in Los Angeles and see the famed signal, you won't have to fear.
The City of Angels will honor the late, great Adam West by illuminating the Bat-Signal for those wanting to pay their respects to TV's original Batman.
Mayor Eric Garcetti and L.A. Police Department Chief Charlie Beck will preside over the ceremony. The public is welcome to attend, and will start at 9PM at City Hall.
West died Friday after a short battle with leukemia. The actor was 88, and recently published a book containing self-made art, and teamed up with Burt Ward and Julie Newmar for an animated Batman movie.
West's family also encourages fans who can't attend the event tonight to donate to the Adam West Memorial Fund for St. Jude Children's Research Hospital.
You can also remember West's legacy by watching Batman on H&I, Saturday mornings at 6AM | 5C.
