This song plainly describes addiction. It describes the relationship you have with the object of addiction. If you carefully read the lyrics it makes perfect sense.
I would extend the interpretation to addiction to drugs, people, things, behaviors, attitudes, habits, and ways of thinking that are fundamentally destructive, and that deny you the possibilities and chances of becoming a greater version of yourself. That is when and how "a green light turns to red" for someone. When he can't discipline and control his impulses and his addiction, so that it dominates and dictates his whole reality, and eventually his life.
I'll just move to the last verse. If you know the first thing about addiction, you know that even if you manage to control it, it is "forever inside you, wherever you go", and the only thing that can change, is your ability to resist it.
