Great quality lights, lightning fast shipping

I have made several purchases from Christmas Light Source in recent years and have never been disappointed. I love my seasonal C9-bulb twinkle lights and had grown frustrated in the difficulty finding traditional incandescent bulbs in local stores recently. (No fan of LEDs here) Fortunately, CLS not only has them, but in a wide variety of styles...and the ordering process is simple with shipping that's always spectacularly quick.
Thanks, Christmas Light Source !

twinkle lights

The lights twinkle ok but I wish they came triple dipped as well. My other lights are triple dipped so they don't match. Out of the box of 25 I ordered, four were broken so the packaging is not adequate.

Exactly what I needed

Exactly what I needed to add to some led bulbs to add some natural twinkle. All in good shape when arrived.

Good...not perfect

Bulbs arrived quickly. One broken...bummer. if the rest work, no big deal. All of the others are undisturbed, strange, but that's mass production???

Jo W. (Torrance, CA)

Twinkling Ornaments

I needed to update several non-twinkling bulbs and older paint faded twinkling bulbs. I was happy to find Christmas light source on line. The multi-color bulb packs came in nicely separated packages. I was even able to reuse with extra saved non-twinkling bulbs that i needed to replace. The light are on 12ft Arborvitae trees that appear as twinkling ornaments. I will shop this site for future use, thanks!


I found this company and will always deal with them. I ordered some C-9 twinkling bulbs. They arrived and I replaced my bulbs. Easy to order, reasonably priced and now they are lighting up the house!
