These are a string of led solar lights with translucent plastic decorative bulb covers. 2 bulb covers came off during unpacking. Several more came off while on display. 
The lights that didn’t lose bulb covers were pretty. However the lights were very dim. You had to be closer to 10 feet to see them. 

We have quite a few solar lights we display outdoors. These were noticeably dimmer than all the others.
