Whether you're lending your patio a touch of vintage-inspired style or rounding out a living room or bedroom with a whimsical accent, a string of plug-in lights like this are a great option for adding a touch of whimsy and relaxed lighting to any space. This string, for example, features 10 included LED bulbs with globe shades for a touch of yesteryear's style. The black cord makes for an understated option that can disappear into a dark space, leaving your lights with a floating look.
