Turn any bottle into an attractive lamp, simply and instantly. The top of this little light looks like a cork; the bottom is an LED that recharges via USB. Unlike a candle stuck in the neck, the LED shines down and illuminates the bottle (especially nice with colored glass), plus it won't drip wax or blow out in a breeze. A simple twist turns it on and off. Use indoors or out. With three or more, you can create a glowing cluster. About 1" wide, 2" long. Set of 3 LED bottle lights. Bottle not included.
