Customer Display: Red and White Glass C7 Bulbs
A Classic Red & White C7 Display That Never Goes Out of Style
Every once in a while, we receive a customer photo that reminds us why Christmas lights are so timeless. This cheerful red-and-white roofline is a perfect example — traditional glass C7 bulbs glowing against a charming home, creating that nostalgic look so many of us grew up with.
We love projects like this because they show that when it comes to Christmas lights, personal preference rules. LEDs may be more common, but there will always be decorators who love the warm glow and vintage feel of incandescent glass bulbs. There’s no “right” choice — just what makes your home feel like Christmas to you.
Beautiful red bulbs. ⭐⭐⭐⭐⭐
“Absolutely love these bulbs. For years I’ve used the mini lights from big box stores. I was wanting to go to a more traditional look. The C7 and C9 bulbs from the stores are just cheap and don’t last too long. These are great. These bulbs are painted red to give the opaque look. They feel durable and look great. Very pleased and will probably order from here from now on.”

Shop C7 Bulbs & CordsFrequently Asked Questions
Do C7 glass bulbs get hot?
C7 incandescent bulbs do warm up during normal operation because they use a filament to create light. That warmth also contributes to their cozy, nostalgic glow. If you prefer a cooler-to-the-touch option, consider C7 LED bulbs, which stay much cooler while still looking festive.
How many C7 bulbs do I need for my house?
Most rooflines use bulbs spaced at 12 inches. Simply measure the edges you want to outline and match that number to your bulb count — one foot equals one bulb. It’s always smart to order a few extras for backup.
LED vs. glass incandescent — which should I choose?
Glass C7 bulbs give you that classic, traditional Christmas look many of us remember. LED bulbs use less power and run cooler. There’s no wrong choice — it’s all about the style and glow you love most.
Can I mix colors, like this red and white pattern?
Absolutely! Alternating red and white is one of the most popular patterns after solid white. You can also get creative with patterns for holidays, sports teams, or just what makes your home feel merry and bright.
