Opening Fuse Door in a Christmas Light Plug
How to Open the Tiny Fuse Door on a Christmas Light Plug
(Yes, we finally filmed it up close!)
After dozens of comments asking “Wait… how do you actually pop that little door open?”, Shellie grabbed the camera and a screwdriver.
30 seconds that will save you 10 minutes of frustration
Pro Tips from the Video
- Use a small flat-head or stubby screwdriver — easier on your palm!
- Slide the tip into the notch and gently pry toward the prongs
- If it fights you, wiggle side-to-side — the plastic lip can get slightly offset
- Spare fuses are hiding right inside (most plugs include two extras)
Still not opening?
The door might be heat-sealed from years of storage. A tiny drop of rubbing alcohol around the seam usually loosens it.
Lost your spare fuses?
Grab 3-amp 5×20mm glass fuses (the exact size used in 99% of mini-light plugs) at any auto-parts store, hardware store, or big-box retailer — usually under $3 for a pack.
Pro tip: keep a handful in your Christmas box every year — you’ll thank yourself in December!
You’ve got this!
One little door = one fully working string of lights.
