We have a metal decorative cactus in our yard. We have had it several years and use solar lights to display it at night. We received a 2 pack of lights and foolishly I picked one strand of lights and tie wraps to secure the lights to the cactus. I was disappointed that when it got dark there were no lights. Waited until the next evening figuring that maybe an extra day of solar would help. It did not. I put the other strand of lights out in the yard without attaching them to anything. They seem to work just fine. Wish I had not wasted my time attaching the bad strand to the cactus.
