The Ghost Traffic Light is a sunken traffic light located deep underwater beside Flint Range. The myth is of a ghostly traffic light that attacks the player when they swim near it.
This myth could be plausible, as a lot of players believe they never saw this kind of traffic light underwater. Also, there is no reasonable explanation on what a traffic light could be doing in deep waters of San Andreas. Some people could say in defense that it is most likely misplaced on Rockstar's behalf rather than a myth.
