Transparent C9 Bulbs




Incandescent, glass, C9 bulbs have been a Christmas light display staple for over 60 years. Use these classic bulbs to create a new display or replace a few broken bulbs to restore your sets for the next holiday season. With brilliant, traditional colors, these are also an economical choice for lighting patios, parties, and receptions. After choosing your bulbs, select a C9 Christmas light cord if you don't already have one on hand. Match green, white, brown, or black 18 AWG wiring to your project background or trim.
