I designed this tree so that you can insert LEDs inside it, which will be powered by 2 AA or CR2032 batteries, depending on the LEDs you have or decide to buy, (I leave the links to both versions), please note that the base is able to accommodate both versions, in addition you will need a piece of double-sided tape or two drops of super glue to secure the battery pack, (personally I recommend using the version that uses CR2032 batteries for its versatility)
