> In my experience, they turn on at night and turn off a few hours later when the battery has run out. But that’s perfectly adequate for what I use them for (Christmas decoration).

The decorations I bought have several modes. One press of the button turns on the lights for 6 hours, then off for 18. Repeat. They have been working for 2 weeks on very small batteries. A 50 light string, timer and battery for $2.99.

In a similar vein, I bought some LED headlights for my golf cart. I was looking over the driving/fog light selections in Autozone and noticed the boxes have a “TRY ME” button. Not really thinking, i pushed the button while looking at the light. Wow! Full brightness from just a little disc battery. And the battery and switch ( a real push button switch with knob, not just a couple of metal strips) are cheap enough to toss.

Here’s something interesting, by which I mean kind of frightening. Ever since I started this thread, I’ve been getting advertisements for solar and battery powered Christmas lights on the web pages I go to. I could almost understand it if I clicked on any of the links in the thread or searched for them, although I’ve done everything I know to keep Google and the likes from tracking me like that. Creepy.
