There are two type -- one has a small solar panel off to one side, wired to the light; the opther has the solar panel built into the cap above the light. They use LEDS, which is why they work at all, as incandescents would drain them in short order.

We've used both types as garden lighting, and the one with the separate panel has been more robust and reliable. These are path lamps on staks that you stick in the ground. But I see no reason a carriage lamp made the same way shoudln't be available.

Look for sturdy build. You can get cheap ones from China which will fold up on you after one winter.
