"Why did you change your mind about leaving?" "They called me their 'light'"
Quoted directly and repeatedly by Michael Caine's character in Interstellar to the point where it becomes a borderline Madness Mantra. He's not raging against his own personal death, but the death of the entire human race. Dr. Mann also quotes it, but for him it really is just about his own personal fear of death.
The title of George R. R. Martin's novel Dying of the Light is taken from this poem. It's appropriate, taking place on a dying planet, among people of a dying culture and revolving around dying or dead relationships. It is not a cheerful novel.
The last stanza appears as an epigraph for the Tennessee Williams play Cat on a Hot Tin Roof, which is about a man whose father is dying.
Quoted in Margaret Laurence's The Stone Angel.
Referenced in the title of the last Skulduggery Pleasant book, The Dying of the Light.

John Cena recites parts of the poem as voiceover for the trailer to WWE 2K15.
This video on the lore of Dark Souls uses the poem to thematically tie into the plight of Gwyn, the Lord of Sunlight. A grand lord who would rather have his soul burn forever than let the dark come, for, in the end, he was nothing but an old man afraid of the dark.
