We've seen our customers are using these twinkle lights in the following ways:
Be sure to purchase the Christmas light clips, hooks and stakes used by professionals across the country for sharp lines and easy installation.
Install these bulbs in your existing C9 cords with E17 (intermediate) bases or choose new cords from our wide variety of lengths, colors and spacing. Tailor your spacing selection and length based on the size of your project.
Be sure to inspect your cords every season and discard them if you see signs of wear and fraying.
Warning: C7 and C9 incandescent bulbs heat up under operation. Do not rest them on heat-sensitive surfaces, next to plastic, or coil them up in such a way that allows the bulbs to rest against the insulation and/or sockets of their cords while they are turned on.
Do not nestle these bulbs into plastic tree limbs. Some of the latest models of plastic Christmas trees have super thin plastic needles that will melt with extended contact with incandescent C7 or C9 bulbs.
We suggest you purchase LED C7 or LED C9 bulbs for this style of tree.
These bulbs should not be covered with fabric or any type of flammable material.
Do not operate lights without supervision. When installed indoors on natural Christmas trees, make sure the tree is well watered, position bulbs so they do not come into contact with needles and limbs and do not operate lights without supervision. Locate an easy to access fire extinguisher near your tree.
