Make The Knight Rider Led Animation

Thank Goodness!

Knight Rider series is alone crimefighter battles the forces of evil with the help of a virtually indestructible and artificially intelligent supercar.

The artificially intelligent supercar is named as a K.I.T.T.. The most prominent feature of K.I.T.T. are the LEDs that slide to the left and right of the front of the car. These leds are very iconic in this TV Series.
