I bought a four pack of really cheap solar lights last year, figuring I would be pitching them real soon. They came with the batteries also, I installed then, stuck them in the ground and they are still working and going strong. The sun recharges them through the little solar panel. Mine just put off a nice glow, not bright, but it is enough to outline the pond at night, which is what I wanted. I may get some prettier ones now, so easy even I can install. LOL
