Outdoor Solar Lights

I have a set of solar lights with rechargeable NiCd batteries. I thought one wasn’t working , but then I discovered it was on during the day, and went out when it got dark. How does that work?

there is a little photo electric eye probably on the top – make sure it is not covered with dirt or anything else… might look like a small round hole or a little domed button… check the lights that work to find it and see if something is different on the ‘bad’ light. If you can not find anything, the light sensor (electric eye) may have shorted out…
