Attention: Make sure your light string uses 2.5 volt 0.425-watt incandescent bulbs and a style D base. These will not work with LED lights. Using these in a light string with the wrong voltage or wattage will burn out the bulb quickly, or not give it enough power to flash your lights. It can take a minute or two for these to warm up enough to make your string flash.
