The Bat-signal will illuminate Los Angeles City Hall Thursday night in honor of late actor Adam West.
In Batman comics, movies and TV shows, the Bat-Signal is a spotlight with the shadow of Batman's winged emblem that is shown on the night sky to call for Batman's help.
The original Batman actor (in the 1960 television series) died Friday at age 88.
Los Angeles Mayor Eric Garcetti will host a tribute to the TV legend at City Hall, beginning at 9 p.m.
