Lee Display's brand new & energy-efficient 35 Bulb Twinkle LED 5MM Mini Dot Christmas Lights Replace those old light bulbs with a brand new set of traditional LED Warm White Christmas Lights! What's the difference between Twinkle or Steady? * Twinkling bulbs have a filament inside the bulb that when heated up by the socket, breaks apart and causes the illusion of a blinking/flashing/twinkling light bulb. * Steady Bulbs stay on continuously while plugged in. No flashing on and off. Each string comes with 35 Lights spaced 6in apart for a total length of 17.5 feet. Bulb Details: * Cord Color: Choose between White or Green String Cord color * Every other 5th Bulb Twinkles, 7 Twinkle Bulbs per set.
