A multi-colored LED biasing circuit that allows users to selectively choose the colors for a given state or condition. A user will assign by use of switches which color of a multi-colored LED will light on the presence of an electronic signal representing a state or condition in need of a visual output. One embodiment for a tri-colored LED will allow a user to select a base color for when no signal is present, the base color selected between a first color, and a second color and a secondary color for when a signal is present, the secondary color selected between the opposite of the base color (first or second color) and a third color. The present invention can be embodied in toys in a variety of ways. For example, dolls and other figurines having eyes that can change color to represent a change of state or condition in the figurine for enhanced play or decorative purposes. One embodiment uses a figurine with tri-color LEDs as eyes and the configurable color selection circuitry to choose the color of the eyes using switches. The three different colors of a tri-colored LED may be achieved through proper switch positioning and each color can be assigned a condition or state by the fertile imagination of a child in order to enhance the play value of the toy. Another embodiment shows use of tri-color LEDs in a toy helicopter to represent a weapons system. Finally, a flying disk is shown outfitted with tri-color LEDs using the biasing circuit to light the LEDS while the disk is in flight thereby causing bands of illumination caused by the spinning disk.
