Red, White and Blue Rattan Star Christmas 10’ String Lights - 2 Sets Would be great for a patriotic themed Christmas tree! New, two boxes 10 feet long, 10 inches between each star. One box has been opened. Needs 3 AA batteries for each set. For indoor use only. The lights are wired to the box, so someone could push the ‘Try Me’ button in the store. So it seems you need to disconnect that to use it with AA batteries and the on/off switch…please see pic.
