9 LED window light in the shape of a red bulb, designed for Christmas decoration. It is battery-powered (included) and has a suction cup for easy hanging on windows. Each light measures 6" in length and 2.5" in width. The lighting technology used is LED. Perfect for adding a festive touch to your home during the holiday season. These flash so it was hard to catch them all lit at the same time. I have two that require batteries that will be included (not photographed).
