These are decent lights, but the instructions are non-existent. Know ahead of time that, unless you cover the solar panel (like i did in one photo), they will not come on til it is DARK. Not dusk, not anytime before dark. I have other solar lights that came on probably half an hour before these. They do NOT come on before it’s very dark. This would’ve been nice to know before purchasing. They do include extra bulbs, which is good as each of the strands I purchased had one bulb not working.
