Lee Display's brand new & energy-efficient Green Solid LED Light Bulbs are sold in a box of 25! Replace those old light bulbs with a brand new set of traditional candelabra-style Green Opaque LED Christmas Lights. Simply screw them into any patio light string and watch them glow with the holiday spirit! Choose between Twinkle or Steady: * LED Twinkling Bulbs are a little different than traditional incandescent twinkling bulbs. LED Twinkle Bulbs contain an oscillator that alternates current on and off to produce a Twinkling, Flashing, or Blinking effect. Contrary to Incandescent Bulbs, LEDs will start twinkling immediately when turned on and last longer than steady bulbs.
