### ⭐⭐⭐⭐⭐ lights are working!
*by O***D on January 28, 2026*

I purchased exterior string lights for my backyard, and following a night of heavy rain, they ceased to function. Upon replacing the fuses, the lights were fully restored. I have also successfully utilized these fuses for my Christmas lights. It is beneficial to maintain a supply of spare fuses for unforeseen circumstances.
