The Traffic Light ghost is a spirit that appears in The Real Ghostbusters Magazine Fall 1989.
When a Class Five poltergeist possesses traffic lights to cause accidents, the Ghostbusters are called in to capture it. After many hours of searching for it in the Ecto-1, the Ghostbusters get rammed by a truck to the influence of the ghost. An angry Ray gets out and fires his proton pack at the possessed traffic light. The poltergeist got away, so the Ghostbusters plan to pretend they are garbage men.
At the height of rush hour in Times Square, the ghost makes its presence known. With the ghost jumping from pole to pole, the Ghostbusters decide to shoot every traffic pole at the same time. It then possessed an electric billboard.
