This solar lights are really neat . I got the white ones and they work great . I like the bulbs on them they are different them the old time Christmas light with the bigger bulbs that break easy . I love the different mode settings this has too .These are made well and are waterproof. You get 100 lights in the string and so pretty when lite up . Use can use these indoor out outside . Right now we put them in my sons room and jimmied up the solar panel out side his window . He loves it and so do i . I really like that they are solar and they come on at night go off in day light . On the back of the solar panel you will find the mode and off/on buttons .They are great quality .
