These are 2.5 volt flasher bulbs. Use one flasher bulb per every 50 lights (or single circuit) to create a "flashing" effect. This will make all lights blink on that circuit (light set goes through a steady blinking ON and OFF). Contains 3 clear FLASHER mini light replacement bulbs.
Note: bulbs come naked without a base. To install, simply remove old bulb from original base by straightening the wires then slide the new 2.5 volt bulb in place and bend the wires back.
2.5 volt, 170 mA, 0.42 watt
