C7 Glass Bulbs

Classic C7 Christmas Bulbs

These lights are great for the following applications:

  • Outlining rooflines
  • Accenting flower beds
  • Wrapping and hanging in trees
  • Making a gazebo festive for your next party

C7 Christmas light bulbs are traditional incandescent glass bulbs that are about 2 inches long from bottom to top with a 1.5 inch long bulb. They have an E12 base - the same base as a night light replacement bulb.

We have had customers call in specifically for this reason because they wanted a pink nightlight for a little girl's room or some other colored bulb to match their color scheme.

If the C7 Christmas light bulb is too small for your application, check out our C9 Christmas light bulbs.

Transparent C7 Bulbs

This is a traditional bulb that is double dipped in transparent pigment. You can see the filament in this light bulb. White or clear C7 bulbs is our most popular seller in this category. Use transparent bulbs for :

  • Outlining rooflines
  • Christmas trees
  • Gazebos
  • Porches and overhangs

Opaque or Painted C7 Bulbs

These replacement bulbs are painted with a flat opaque paint and are a great part of retro decorating for Christmas and parties all year. Try them for:

  • Retro Christmas tree
  • Decorating a wedding tent
  • Store displays
  • Spring decorations - pink, yellow, green and purple are perfect for Easter

Twinkle C7 Bulbs

These transparent bulbs flash on and off approximately once a second. (On a second, off a second.) Use these at a 10% ratio to add sparkle to your transparent display or mix with the same color opaque bulbs for a funky spin on traditional lighting.

We sell our bulbs and stringers separately to allow you to customize your lights for your application. All of our C7 Christmas light bulbs are sold in boxes of 25 bulbs. (What a great value! Most of these types of lights are sold 3 for $.99 in stores as replacement bulbs.)

See our selection of C7 Cords and Spools to complete your sets.

Decorating with C7 Bulbs

A Christmas Tradition

When you take our C7 Christmas Light bulbs out of the bag, you'll be transported back to your childhood in a matter of seconds. There is a special sound these bulbs make when two bulbs come together and that sound means that Christmas has arrived!

Wonderful for Historic Buildings

Victorian homes, historic homes, log homes, and timber homes look stunning when decorated with our old-fashioned style C7 Christmas lights. Because the very style of home is a throw-back to a simpler time, our C7 bulbs are the perfect choice for decorating these homes. Make sure to string the lights along your roofline, eaves, fences, porches, patios, and balconies. Do you have a long country drive or lane that leads to your beautiful historic home? Our light stakes, combined with strings of C7 lights in the color of your choice, will suspend the lights above the ground. Your guests, family, and friends will instantly feel welcomed!

Beautiful During the Day

Our opaque C7 Christmas light bulbs are the ideal choice for any lighting application where you'd like to have the lights on during the daytime hours or the evening hours. The opaque C7 bulbs are painted, so they add color and beauty to your holiday tree, bushes, gardens, or roof line during the day, even when they're not lit. During the evening hours, the same bulbs will provide soft illumination and color when they're burning.


What's a holiday display without a few (or several) twinkle lights? With our C7 twinkle light sets, you can make Santa and his reindeer appear to be moving, light up sections of your display at varying intervals, or simply make all of your trees in the yard sparkle.

Retro Parties

Retro themed parties call for retro lights! Drape, swag, suspend, outline, hang, and wrap our C7 Christmas light bulbs on, over, across, and around your party space to create a throw back atmosphere for your next party.

Accent Landscaping All Year

Highlight the incredible landscape features surrounding your home. Outline your garden, your flowerbeds, and walkways with the C7 bulb color of your choice. Use several coordinating light sets or opt for a multi color set of bulbs that you use to create a custom string of lights to fit your landscape or decorating decor. Stone sculptures, water features, and arbors are all great backdrops for a bit of added color and light, no matter what the season. Don't forget to adorn unassuming shrubs and trees as well.

For More Than Just Christmas

Leave your light cords up year round and simply switch out the bulbs to celebrate the holidays during the year. For Valentine's Day, use the red C7's. St. Patrick's Day begs for the green C7's, of course. Our pastel opaque bulbs are ideal for Easter and Spring. And for the 4th of July, use all three colors of red, white, and blue to make your home the most patriotic looking house on the block.

Bring back a taste of Christmases of yesteryear when you utilize our traditional C7 Christmas light sets to add warmth, light, and a soft glow to your home or business.
