This 3V Button Cell Battery Holder Kit is to be used with the CR2032 Battery (not included). The kit contains the battery holder with an on/off push button switch, 5 LEDs (size 3020), and 2 pieces of shrink tube (1 pc 1/16" and 1 pc 3/32") to protect the connections from making contact with each other. Use the shrink tube that best fits with the number of wires you are connecting by cutting the shrink tube in two pieces. Choose between white light and warm white light. Although this kit only comes with 5 LEDs, you can connect up to 10 3V lights by connecting all the red wires from the lights to the red wire on the power supply and the green wires to the black wire.
