Using these LED disc lights is a breeze. First, insert 4 AA batteries into each light (batteries aren't included, so you'll need to get them separately). Then, place the lights wherever you want - they're perfect under tower vases or as tabletop decorations. Use the remote control to turn them on and off or adjust the settings. For weddings, events, birthdays, or parties, these lights can really add a special touch. When it comes to maintenance, just make sure to replace the batteries when they run out. And remember, one order only includes the lights, not other decorative accessories.
