The little white twinkle lights on my beloved topiary no longer light up. Well, actually, the bottom topiary ball of the three tiered topiary do light, but the top two do not. I'm afraid the string lights are the type when one bulb goes out, they all go out. It was so beautiful when all three balls were lit. However, my sparkle bird is still delighted to be perched atop. And, I am still delighted, twinkle lights or no twinkle lights.
