Why are there two fuses in Christmas lights?
Typically, these strings of lights have two tiny fuses, one in each side of the AC line, located inside the AC plug. The fuses are intended to melt or “blow” before the copper wires in the string could melt or cause a fire from overload. … Sometimes the instructions with the lights say, for example: “DO NOT OVERLOAD.
What do you do when Christmas lights burn out?
Give them to charity If you can’t find a place to recycle, there is a charity called the Christmas Light Recycling Program that takes old lights (including broken ones), recycles them and uses the money to buy books and toys for less advantaged children.
Why are half string lights out?
A light bulb has come out of its socket or is half out of its socket and it has brought down the circuit. For light strings that commonly have over 50 bulbs, they are constructed in 2 or more continuous circuits. If a bulb is missing in a circuit only the bulbs in series of it will go out.
What causes half a string of LED lights to go out?
If one of your LED light strands isn’t working, it’s probably just because it has a bad bulb. If one bulb dies, it can cause the rest of the strand to stop working.

How do you fix a bad shunt?
A faulty shunt may sound like a catastrophic failure, but you can often fix it with the LightKeeper Pro. Simply plug in the light strand and remove a bulb that’s in or near the dark section. Next, insert the tool into the bulb’s socket and squeeze the trigger to activate a piezo circuit.
What is a defective bulb shunt?
Most miniature Holiday Light set failures occur when an individual bulb “shunt” fails to energize. These shunts are energized when a filament burns out. This causes a section of lights, usually 35 or 50, to go out instead of just one light bulb.
Do all Christmas lights flash?

Short answer: No, if a bulb burns out, the rest of the lights should stay lit. Replace the burned out bulb as soon as possible to extend the lifespan of the remaining bulbs. If the light string has gone out, it means a bulb is halfway or fully out of it’s socket and has broken the circuit.
What will happen when one bulb of the series Christmas light is busted?
If one bulb goes out, no current flows in the circuit as the blown out bulb acts as an infinite resistance. (Two wires separated by air in between them). So other bulbs stop emitting light as well. If one bulb goes out, the other bulbs are unaffected as current still flows through the other bulbs.
