Twinkle Lites are our specialized C9 LED bulbs made to replicate the random effect of incandescent twinkle bulbs. They flash on and off randomly every few seconds, and because C9 sockets are powered individually, each bulb will "animate" independently of one another.
We've done our best to make them as similar to incandescents as possible, so it's unlikely you'll ever find multiple bulbs synced up with one another, and in the event that they do, they will quickly fall back out of sync, just like incandescents twinkle bulbs would.
Our Twinkle Lites are also Dura-Bulbs, which offer benefits over our glass bulbs, such as being shatterproof, more colorfast and weathertight.
Because of their additional internal circuitry that helps them flash on and off randomly, Twinkle Lites cannot be used in conjunction with a dimmer.
Twinkle Lites are available in both Jeweltone and Candleglow versions. We currently only offer Twinkle Lites in C9 sizes, but plan to add C7 versions to our lineup for the 2026 holiday season.
