I think the green light on Daisy’s dock symbolizes a path or a glowing beacon of hope for Gatsby. Because in chapter 1 Nick Carraway narrates he saw Gatsby reach towards it. To me the green light represents wealth like money and the light as something to lead him towards his goal. Also, throughout the book, it was not written that the green light stopped glowing, so this is a sign that Gatsby never truly attained his dream of becoming rich and died trying to. I thought the author, Scott Fitzgerald was clever to incorporate the light because it can be seen to be so close to Gatsby, almost touchable yet still far away as his dream looms over him, daunting him.
