Perfect size. Great that this company is out there. Auto stores don’t sell this size of a fuse.

These fuses are good. I was able to fix an old unworking string of Christmas lights. They saved me a lot of money by my not needing to purchase an entirely new set of lights.

Works great for what I need

My outdoor Christmas lights were having problems staying lit, and as I ran out of spare fuses which are normally included on each strand...I needed more and these fit the bill. Plus I have enough extra ones for next season too.

Replacing fuses for blown Christmas light sets can be a bit of a hassle, but it sure beats the alternative of throwing away an entire set and having to hunt for a set that matches your household display, which can often be difficult if it's a style that isn't mass-produced anymore. Was very happy to find this pack of fuses, and at a very modest price, as many of the businesses that used to sell this type of item are no longer in business. Very highly recommended for anyone who has a lot of stringed lights on their home, for Christmas or any other sort of holiday...
