The display includes an illumination circuit carried aboard the display, comprising a battery cell, a plurality of light emitting diodes, electrical conductors connecting the battery cell to the plurality of light emitting diodes, and a switch accessible to the user. The, wherein the switch is operable to open and close the illumination circuit.
