In addition to the green lights representation of the love Gatsby and Daisy once had, the green light can also symbolise the unattainable dream. In Gatsby’s case, Daisy was the unattainable dream. The novel ends with Nick saying how much “Gatsby believed in the green light, the orgastic future that year by year recedes before us. It eluded us then, but that’s no matter – to-morrow we will run farther, stretch out our arms farther…” (Fitzgerald 180). Its odd to think as the light as a representation of both the past and future. While it reminded Gatsby of the past with Daisy, it also gave him hope to recapture that past in the future.
