We love the look of these traditional glass twinkle bulbs. Mix a handful with stead-on bulbs or go over the top with 100% twinkle. Note that these bulbs flash on and off randomly to create their twinkle effect. There is not a fading aspect to their operation.
Please take note that both C7 (E12-sized base) and C9 (E17-sized base) glass twinkle bulbs are listed on this page. The size is listed in the product title and on each product's detail page.
Not sure which size to choose? A C7/E12 base is the same size as a night light. A C9/E17 base is slightly larger.
This blog post shows the bulbs next to each other for size reference.
