Abstract
An illuminated natural gas display panel assembly simulates the generation and transmission of natural gas to different classes of users by means of a plurality of elongated strips of light-transmitting arrays, each strip made up of a plurality of LEDs and with different light-sequencing circuits for individually controlling the rate and direction of sequencing of the lights to represent a desired pressure level and direction of flow along each said array; and different colored light elements are employed to aid in giving the optical illusion of different pressure levels along each of the light-transmitting arrays.
