What is claimed is: 1. A light card comprising: a thin card body that generally extends in a plane; opposite surfaces of the card body; a surface mount LED mounted to the card body to project light from at least one of the opposite surfaces thereof; electrical contacts of the surface mount LED; a thin power source mounted to the card body; and a switch bar mounted to the card body operable to be shifted in a direction transverse to the plane of the card body to selectively provide power from the power source to the LED for generating light therefrom. 2. The light card of claim 1 wherein the switch bar is of resilient conductive material. 3. The light card of claim 1 wherein the switch bar has opposite ends that are both spaced from the LED contacts. 4. The light card of claim 1 wherein the switch bar has opposite ends including one end fixed relative to the card body and the other end cantilevered therefrom extending over and spaced from the power source. 5. The light card of claim 4 wherein the fixed end of the switch bar is spaced from the LED contacts. 6. The light card of claim 4 wherein the power source comprises a pair of disc batteries each having positive and negative electrically conductive sides that are arranged oppositely to each other relative to the card body with the fixed end of the switch bar attached to the negative side on one of the disc batteries and the cantilevered end spaced over the positive side of the other disc battery. 7. The light card of claim 1 wherein the switch bar includes an end for being pushed toward the power source and the switch bar end is adjacent the one surface of the card body from which light of the LED is projected. 8. The light card of claim 7 including an insulator member between the switch bar end and the power source with the insulator member including an opening into which the switch bar end is pushed to energize the LED. 9. The light card of claim 1 wherein the card body has peripheral edges and the surface mount LED is spaced from the card body edges. 10. The light card of claim 1 wherein the card body includes at least one opening, and a lens in the opening for providing enhanced viewing therethrough. 11. The light card of claim 10 wherein the at least one opening comprises a pair of laterally spaced openings, the lens comprises a pair of lenses with one lens in each opening, and the LED is aligned with an area generally between the spaced lenses to provide illuminated viewing through the lenses. 12. A light card comprising: a thin card body of generally rigid material; an LED mounted to the card body; a thin power source mounted to the card body; a conductive switch bar distinct from the LED and the card body, the conductive switch bar having an elongate and substantially thin, flat configuration extending along the card body and being of flexible, shape-retentive material; and opposite ends of the switch bar with one end fixed relative to the card body and the other end cantilevered from the fixed end with the cantilevered end and flat configuration of the switch bar permitting ease in pushing of the switch bar cantilevered end for energizing the LED with power from the power source. 13. The light card of claim 12 wherein the LED includes electrical conductors that remain fixed as the switch bar cantilevered end is pushed. 14. The light card of claim 12 wherein the LED is a surface mount LED including electrical contacts spaced from the cantilevered end of the switch bar. 15. The light card of claim 12 wherein the card body includes opposite surfaces and the surface mount LED projects a cone of light having an axis that extends transverse to at least one of the card body surfaces. 16. The light card of claim 12 wherein the thin power source comprises a pair of disc batteries, and a pair of elongate and flat conductor bars mounted to the card body with each conductor bar extending from the LED to one of the pair of disc batteries.
