One of our favorite ways to add extra sparkle to a Christmas light display, mix at a subtle 10-20% or go all out and install them at a 100% rate along a roofline. We enjoy using white twinkle bulbs mixed with steady-on to wrap trees. In winter, the lights have twice the impact on bare branches.

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!

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.

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.
