Great service

Nice lights, fast delivery

25 incandescent C7 bulbs., 5 different colors. I like the effect of each bulb flashing independently and at different rates. I thought the price was reasonable and they were delivered in 2 days - very fast. Thanks, guys! I look forward to working with you again.

I love them.

I received my order and they work perfectly. They are even the true colors of my other twinkle lights. I had previously ordered from a competitor and the lights didn't twinkle nor did they have the true colors that I am used to. I have your site bookmarked for ordering future items.

Love these bulbs!

This is my third purchase of the C7 twinkle light bulbs from Christmas light source. Shipping is very prompt and the price is the best I have found for these difficult to find light bulbs. Package arrived well packed and the bulbs last! I am a forever customer! Thank you!

Long lost has been found

My parents have a ceramic hunted house that they made 20+ years ago, it had two of these flashing bulbs, one burned out years ago, couldn't find a replacement and had to replace it with a solid bulb, the second flashing bulb burnt out this year prompting renewed search. Ordered these bulbs, the haunted house has never looked better.

Old style Christmas

Thanks for still carrying these twinkle bulbs. They are getting harder to find now with the LED lights. We love our old fashioned lighted tree!
