Looking for a play. It's about the writing staff of a fictional TV show, I think a sitcom. The protagonist is female. (And I think the playwright is too, and possibly the protagonist is the playwright's stand-in). Other characters: a Norman Lear-esque showrunner, and an ex-NCAA basketball player staff writer.

I'm looking for major theatrical plays, set no later than 1950, that feature a lamp, flashlight, or other luminous prop as important to the story. If possible, please summarize the prop's usage including where in the story the prop is used. Thanks in advance!
