Classic White Twinkle Bulbs

We love the classic look of these white twinkle bulbs. They are a real Christmas classic and add a lovely amount of twinkle to any light display.

Twinkle bulbs work by randomly flashing on and off. The flash rate is dependent on the temperature, so the bulbs will flash slower in cold weather. It may also take a few minutes for the bulbs to start to flash after they are plugged in. Be patient, it will happen!

To get the best twinkling effect, we recommend mixing twinkle bulbs with solid-color bulbs. A good starting point is to use 10-20% twinkle bulbs. You can adjust the amount of twinkle to your liking.

We hope you enjoy using these classic white twinkle bulbs to create a beautiful and festive Christmas light display!

Hard to find twinkle bulbs!

Wasted a lot of time looking for the twinkle lights for our C7 strands and will order anytime I have replacement needs. Packed well for shipping and arrived in a few days. Great price and service! I worked in visual merchandising for years and this is the best source and prices around. Twinkling has returned to our home!

No twinkle only blink

The bulbs blink not twinkle which is disappointing

Perfect for my Twinkle Bells

I found an old set of red plastic bells while clearing out my parent's attic. They brought back childhood memories of when my mom would hang them on the front door for Christmas. Your replacement bulbs have them working perfectly - just like I recalled. I'm thrilled to have a piece of "Home" hanging in my kitchen window. Thank you so much!

Excellent Product!

I used these bulbs in a set of vintage, plastic bells. They twinkle just as described and make the bells look like they're moving. The packaging and bulbs arrived in excellent condition and were shipped in a timely manner. I would definitely order from this company again. The only issue I have is with the warehouse charge because my order was under $20.

Twinkling Bells were saved

The Twinkling bells were a yearly staple in the front windows of our home. The last few years, we could not find the twinkling light bulbs and used regular bulbs. Found you bulbs and put the in, The twinkling has begun again! the neighbors even stopped and commented that they had missed the blinking all these years. We are thrilled. Fast shipping and delivery.

Perfect replacement

I got a bunch of Christmas light strings from my mother and ordered these to replace the broken bulbs. These worked great - just like the originals! I'll just remember to order an extra box or two next time.

approximate shipping cost to 05701 for 1 set of clear twinkle, C7, 7 watt@ 25 bulbs, AND, when do you think the clear Twinkle C7 7 watt bulbs will become available again?

It is about $12 or so to ship a box of 25 bulbs to most US addresses. If you put a box of bulbs in your cart, there is a shipping estimator on the cart page where the system will quote all the available shipping options with FEDEX and UPS.
We estimate that most items will be back in stock in August/September. Of course, there are many factors outside our control. Sign up for the waiting list and you'll receive an email as soon as they are received.
You might consider ordering more than a single box to make the shipping less a percentage of the cost of the bulbs and as a hedge against any price changes in the next season.
You are wise to be shopping now! We thing 2025 will be a record season for Christmas lights.
Let us know if you have other questions. Have a great summer.
