Irresistibly invites young audiences to holler along. . . and to let their own lights shine. A stopper for readers ready. . . and set to . . . GO! -- Kirkus Reviews (starred review)

With a wink of humor and a lot of heart, it's a story that sheds a moving light, so to speak, on powerful mantras of self-acceptance, awareness, and appreciation. -- Publishers Weekly (starred review)

Much like Carzoo's forlorn fire hydrant (who makes an appearance here) in Lou (BCCB 06/22), Greenlight makes for a charming protagonist with relatable insecurities, while the premise invites readers in on the joke and gives nuance to what seems like a straightforward message. . . The book emphasizes the value in determining one's own worth, but it also points to the possibility that others see our strengths in ways that we do not. . . This would pair nicely with the aforementioned Lou to lend an emotional/social learning element to a traffic-focused storytime. -- Bulletin of the Center for Children's Books
