I bought these a lot of them, to have onmy patioTo give it Romantic feel, with the outside curtains to hang I got , excited to be able to see them lit nightly, I have a pole latern in my front yard I circled it and light inside the glass covers don'f work ,so then , I put some  in that , looked great but only lasted for that night , I guess they need to  be turned off during the day, I thought they would last like Christmas lights so only smaller , looked really great and the beaded light in the latern looked like had lights on only like specks of  light , now will Have to unwind , could replace batteries but costly and need to unscrew tiny screws to take out old ones , if that is  how to revive them , I would hate to think They were  good for one to two days if you turn switch off . If giving a special event or company very  nice , I guess i was thinking I have solar lighted lantern hanging with baskets going to my back yard which light at night leading the pathway to my garden area,
