Add a little twinkle with our Warm Bulb Twinkle Lights to your holiday decor! Lights have 10 twinkling bulbs on a 72" silver cord. A built in timer is great for hard to reach places leaving lights on for 6 hours, then off for 18 hours, repeating daily. Bulbs have a slow twinkle flash and have a crackled finish. Lights are battery powered and requires 3 AA batteries (not included). Each bulbs measures 1" high.
