Most of the times, when Christmas lights stop working, it's because one of the bulbs has burned out.
So in order to find out which bulb is the burned one, you only need to test the connection points in each bulb. And to do that, you need a double ended needle, which will allow you to pinch each wire that goes to the bulb and short circuit that specific bulb.
When properly inserted, the needle will allow current to flow, bypassing the burned bulb, and letting you know that this is your problematic bulb.
That's what I do in the beginning of the video. I take a single point needle and sharpen it to make it a double point needle, and then insert it in an insulating tube so I can hold it safely.
Now if there are more than one bulbs that are burned, this technique may not work. This works fine when only one bulb is burned. So be aware of that too.
And when you find that one bulb that is blown....what do you do? Well, you can replace it, if you have spares, or you can simply remove it by just connecting the wires.
Now be very careful at that point. When twisting the wires, it is best to cover them with something reliably insulating, like heatshirnk tubing (highly recomended).
Also liquid electrical tape works fine and self voulcanizing tape has good results, and as a last resort, the humble insulating tape could be used.
But be very careful of that connection point. It will carry 220V AC so it needs to be properly insulated.
Also, never supply 220V AC to a sinlge one of those bulbs. It can't handle it. These lights are usualy designed to work in series, and take 220V AC running in all of them together, so if one is burned, it's no big deal, you can short circuit that bulb and leave that position empty, but if more than one is burned, then some may need to be replaced.
When working with electricity, always wear gloves and take the proper precautions. And of course disconnect the power.
