The warm, honeyed glow of a true incandescent bulb is the light most of us actually mean when we say the words Christmas lights. This collection keeps that glow alive with replacement bulbs across all the classic sizes, from window-candle small to patio-globe generous.

Every Size, Every Color
Browse candelabra replacements, transparent globe bulbs in eight colors, twinkle bulbs, berry bulbs, and patio-grade G50s in clear or frosted, alongside the socket strands to run them on. Whether you are refreshing a strand from last season or restoring a vintage set that has been in the family longer than some of the family members have, the right bulb is likely on this page. Twinkle variants mix into steady strands for a little motion, and satin and opaque finishes soften the glow where transparent bulbs feel too bright.

Shop by Size
Jump straight to the size your strand takes: C7 bulbs for night lights and window candles, C9 bulbs for rooflines and big outdoor color, or G50 globes for patio strands. Not sure what you have? Our types of Christmas lights guide makes the sizes make sense.
