C7 is the friendly middle child of Christmas bulbs: bigger than a mini, gentler than a C9, and the classic fit for window candles, night lights, and porch strands. Browse traditional C7 replacement bulbs in transparent and opaque finishes, twinkle versions for a little motion, night light replacements, and C7 socket strands in brown for custom runs. Keep a few spares taped inside the decorations box and future-you will be grateful. Transparent bulbs sparkle, opaque ones glow with that soft ceramic look from childhood windowsills, and the twinkle variants keep a candolier lively in the front window. Between window candles, night lights, and porch runs, most houses use more C7s than they realize until one goes dark. See every size in incandescent bulbs, or call St. Nick’s at 1-800-875-8865.
