And if you re buying new lights consider upgrading to led christmas lights.
Led christmas light strand not working.
When working correctly there is a wire shunt in the string that bypasses each of the individual light bulb sockets.
I inspected the wire for.
Led stands for light emitting diode and the colors they produce are both stronger and purer than dye coated incandescent lamps.
If after all the testing the light string still doesn t illuminate it s time to get some new lights.
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.
Christmas lights are the strings of little electric light bulbs often used on christmas trees or to decorate homes or yards.
A wide range of strings are available but this article is about the new led bulb strings.
This year however a bunch of the bulbs did not light up right in the middle of them all as my wife quickly informed me.

Some christmas light testers work by having you slide each christmas light bulb through a hole.
I discovered it before i put it up on the eaves.
As i mentioned earlier the removal of a light will increase the current and led s do not like high current.
The christmas light tester will indicate which bulbs are bad and need to be replaced.
To fix christmas lights if the entire string goes out start by unplugging the string and opening the fuse case which is the plastic box attached to the electrical prongs.
This is how i fixed many led string lights.
If a fuse is black or has a broken wire inside gently pry out the blown fuse with a thin screwdriver.
If this is your problem carefully replace the bulb after first unplugging the string of lights.
With the faulty led light removed the light string half that did not work is now working minus 1 light.
It s a tedious task but an assured way to find the problem and bring light life back to the non working string o.
