I found solar lights at Walmart that were pretty much the same size as the top of a canning jar. I bought a box of a dozen clear generic canning jars at Walmart. And I bought bags of flat florist gems at the dollar store.
I removed the cylinder with the ground spike from the solar light and put a thin line of clear silicone caulk around the outside of the jar ring then put the light on top. After the caulk dried attach flat florist gems around the jar ring and around the little edge at the bottom of the clear shade of the solar light. Then I threw in about 50 florist gems inside the jar for stability outside along my wall. I wanted to use red gems but they didn't have any. Next trip to the Dollar Store :)
