Place hot glue around the base of the solar light. UPDATE: instead of hot glue, it's recommended to use Gorilla Glue or marine sealant. These are weather-resistant adhesives that will yield long-lasting results. Hot glue solar lights onto candle holders.
Step 2: Slide the Solar Light Through the Ring & Keep It Snug. Grab the jar and unscrew the lid. Remove the flat part of the lid and just keep the ring. The top part of the solar light should slide through the ring nicely with a little bit of snugness. In order to make sure the light doesn't fall down into the jar, you'll need to put the foam tape around the top of the light. This will keep it snug.
