How to Change Fuses on LED Lights

September 21, 2019
Christmas Decorating Tips Informational October

One of the most frustrating things about holiday decorating is pulling Christmas lights out of storage and discovering they aren’t lighting up. LED string lights last a long time and will sometimes out last the fuse so checking to see if the LED light string fuse has failed can save your set of lights. It is quick and easy to change Christmas light fuses and get your holiday decorating back on track.

Important Note: Always unplug your Christmas lights before attempting to examine or change a fuse.

1. Find the replacement fuses in a small plastic bag
attached to the female end of your light strand.

2. The fuse compartment will then be on the male
end of your light strand. Take the male end of the
strand and press down with your fingernail or a flat
screwdriver, pushing forward towards the prongs.

3. The top will slide open revealing two fuses.

4. Remove both fuses. The fuses may just gently
fall into your hand, if not, you should try gently
tapping the plug against your hand. If that doesn’t
work, you may need to carefully pry them out using
a small screwdriver.

5. Insert the new fuses.

6. Slide the little fuse compartment door closed.

7. You are now ready to enjoy your
light strand once again.

 

 Once you have all of you strands working, you can resume your holiday decorating.

Another decorating issue that people often run into is, how many lights do you need for a tree? Holiday LEDs has created a guide to help you solve this problem and get your tree looking its best.

Start by measuring the height of your tree. You want to measure from the top point of the tree all the way down to the base, ignoring the height of the trunk. Find the size of your tree and the type of light you are using on the chart below.

M5 lights are the mini lights you may be familiar with. G12 bulbs are raspberry shaped. 5MM (or rice) lights are small but shine brightly at a wide angle. C6 bulbs are strawberry shaped.

C7 and C9 bulbs have the traditional shape you might have grown up with—larger than the strawberry-shaped C6, with the C9 the largest of all. C7 and C9 come in string light versions as well as replacement bulbs. We have a large selection of replacement bulbs and accessories.

Now that you have your light strands working and you know what size/shape and how many you need for your tree, you’re ready to decorate!
