Glen A. Larson was king of the 80's action/sci-fi series. In an interview on the Sci-Fi channel "Sciography" of Battlestar Galactica he said that people loved the Cylons, especially the little red light that moved back and forth on the front of their heads. Not wanting to throw away a good gimmick, he reused that element with Knight Rider, giving KITT that little trademark "one-dimensional pong" light. It was by far, his coolest feature, it's how you knew he was super-intelligent.
