The electric glow on neon acts like a flag, to signal awareness and attention. If attached to a corporation, the neon lights have specific colours and specific design, like a flag code.
In the closing scene, where the artificially cloned human is set to expire, the neon lights are visible in the background.
This powerful scene reminds us of the precious gift we receive each year of our living. The protagonist of the story Harrison Ford, has normal, long, and free life compared to industrially created short lived slave unit. The long lived normal human was assigned to terminate the rouge units, but he, the repo-man lost the fight. When the repo-man is about to fall to his death, he chose scorn and contempt as to spit in the face of the genetically altered humanoid. However the humanoid slave unit chose to save the repo-assassin man's life. This scene demonstrates the mechanism of salvation with regard to the wake of mercy, and hope of holding grace at the moment of one's death. Such grace in legend or reality is always worthy of honor within our collective memory.
