How to Fix Christmas Lights to Reduce Christmas Waste

I love Christmas. I really do. It’s one of my favorite holidays. I love the Christmas carols. I love the tree. And, I love the presents and food. There is only one thing that I don’t like about Christmas and that’s the waste.

 I like to think that I’m a fairly green, eco-friendly person. I recycle everything I can and I try to keep my carbon footprint as low as possible.  Even for someone who tries to make green choices, reducing Christmas waste is something that’s a challenge.  But, I had no idea you could fix Christmas lights.

There are a lot of things that get thrown out around the holidays. Gifts seem to come with so much extra packaging that a lot gets thrown out. Even if you try to re-use the wrapping paper or gift bags, there is always something that needs to be thrown away or recycled when possible.

We try not to buy many disposables in order to reduce waste but one thing has always frustrated me. What do you do with a string of Christmas lights when it stops working properly? I hate that. Do you know how to fix Christmas lights?

How to fix Christmas lights that won’t come on

I’m sure I’m not the only person that goes through a new set of Christmas lights every year. I swear there are little gremlins that secretly break them when I pack them away.

Why do they stop working? I learned that Christmas lights can stop working for a number of reasons: a loose bulb, broken bulb, contact issue or a break that keeps the electricity from flowing through the entire light set.

Do you know how to know which bulb is out on the Christmas lights? You need this.

How to find the bad bulb on Chrismas lights

If you plug in the lights and one bulb is out, it may simply need to be tightened or replaced. You can remove and test the bulb and see if that fixes the problem.

Most of the time, it’s not that simple. If that doesn’t fix the lights, the problem may be that there is a shunt issue or broken filament.  

When that’s the case, I generally give up and toss the whole string of lights and buy a new one. NOT an eco-friendly option but I had no idea what else to do to fix Christmas lights. Until now.
