Using these LED lighted tree twig lights is super easy. First, you'll need to get 3 AA batteries for each battery pack (since they're not included). Pop the batteries into the battery pack attached to each bush. Then, find the perfect spot for your lights. They're great for sprucing up weddings, parties, birthdays, or just as a table decoration. For best results, place them in a dark area so the white - warm white glow really stands out. When it comes to maintenance, keep the battery packs dry. If the lights start to dim, it's probably time to replace the batteries. And when you're not using them, store them in a cool, dry place to keep them in good condition for your next event.
