Smaller Christmas Light Style Stringer Wire
Retrofitting or using a light cord with smaller sockets than a commercial cord?
As a first step, grab a night light bulb. If it fits, you'll need a bulb with an E12 (candelabra) sized base. It's 12mm across.
If that's too small, you might have an E17 base then your socket is the same sized as the bases on a standard C9 Christmas light bulb. That's 17mm across.
After you've detemined the size of your bulb's base, head over to our selection of replacement bulbs to choose your favorite look.
