If this is your problem carefully replace the bulb after first unplugging the string of lights.
Led christmas lights half strand out.
I d try and replace the first dead bulb or if you can t find replacements you could try just linking the connectors by shorting them and.
As the link cannot carry on further than the busted bulb.
Check the entire strand of lights for a missing damaged or abnormal looking bulb according to the christmas light company website.
You may find that the bulb has a black or silver looking stain on the inside.
And if you re buying new lights consider upgrading to led christmas lights.
The christmas light tester will indicate which bulbs are bad and need to be replaced.
I took out each light staring at the end and i found one with a wire broken off of the bulb.
I put a new bulb in and boom fixed.
I ve never worked with that brand of lighting before but usually with christmas lights the are all interlinked as a loop circuit so the first one that is out is usually the cause of the problem.
If after all the testing the light string still doesn t illuminate it s time to get some new lights.
There was no way i was going to replace the entire string so i went online to see what kind of solution might present itself.
Incandescent christmas tree lights aka mini lights are wired in series so if your lights go partially out you have one of three issues.
Sixty bulb led christmas lights are built from two half strings of 30 bulbs each.
I hade the same problem on a set of ge led lights.
Second half of strand was out.
Second test the christmas light bulbs with an inexpensive tester available where holiday lights are sold and online usually changing a problem bulb or tightening it will fix the entire strand.
The first several search results made me gag.
Thanks to everyone for the help.
