Answer:
They use a metaphor.
Explanation:
When an author uses figurative language, he includes certain figures of speech in his work, to make his idea more persuasive. In "Blinding lights", a Canadian author known as The Weeknd uses this kind of language to express his feelings. The very title of the song "Blinding lights" is a metaphor. The lights he is blinded by representing the unfavorable circumstances of not being with the woman he loves. These lights represent his suffering, the obstacles he faces, and generally everything that he wishes he could change.
