Pre-lit Christmas Tree Bulbs Not Working

Make Sure All Bulbs Tight

By

It is very important to make certain that none of the bulbs are loose. That is usually the problem. They can become loosened in shipment or just getting them out of the box and putting them up. If you have ONE bad bulb and it's still in tight, the others will remain lit, and of course check the fuses in the plug, if all else fails...

Check the Fuse

It may be a fuse in the light set. They have a fuse in the line. Check what kind and most drugstores and walmart sale them. Sometimes you can get one out of another old set of lights.

I had the same problem with my tree last year. In each string there is a master bulb. If it goes out, all others on that string will go out with no ability to fix that bulb. It is a permanent bulb. Mine is marked from the factory with a white ring around the base. We contacted the manufacturer and they initially offered to send me a new string. (They are individually identified by number) I complained that the reason I bought a pre lit tree was because I did not want to string it myself in the first place. They gave me a number to give to Lowes and the tree was replaced for free.
However, now my new tree has two strings out.

I replaced the fuse in mine and it did not solve the problem; lights still out on part of a section. False advertising when they say one light goes out and the rest stay lit. Frustrating.
