The embodiments of the invention are directed to a method and apparatus to generate pulsing lights where parameters such as frequency, degree of brightness, and the number of pulses vary depending on the duration of the brake pedal application, the time interval between consecutive brake applications, and the deceleration rate of the vehicle, as well as optionally its distance from other vehicles. The apparatus includes a heated seal bar and a seal bar anvil. The cables attach to an end-effector that grips an object and affects desired movements as directed by an operator through a computer controlled graphical user interface using pointing directives such as put that there.
