Insert the plastic and metal end of the LED into the socket you pulled it out of until it is firmly in place. The plastic covering of the lamp should be pointing away from the socket.
What is an LED light?
LED stands for light emitting diode and refers to a lighting element that is purer and stronger than regular incandescent light. LED lights are commonly found in long strings of lights used at Christmas and other holidays for decoration. You may find that some LEDs stop working, and this causes many people to dispose of the entire string.
How to test if LED chip is faulty?
To test the Failed chip, You simply plug in your LED panel and short each individual LED chip. Shorting a Failed LED chip will cause board to start glowing sans the faulty chip. Other Safer method is to use a small 3v Power source (Like 2x AA batteries) and hook up Thin probles to the output.
What happens if you short out an LED panel?
If all faulty chips have been shorted out, rest of the panel should glow right up. Usually shorting 2~3 chips over the entire count of LED chips will have no detrimental effect. Because the LED panel is wired in series, it will keep the current same across all chips. Your Panel wattage will decrease slightly.
What voltage do LED chips have?
Now the way these LED chips are laid out are usually very simple. All the LEDs have forward voltage of about 3.2V and are connected in Series. Chip boad failures means its just one or two LEDs have failed, causing entire board to not glow.

Step 1: WARNING: Mains Electricity!
This project involves dealing with mains voltage! Extreme care should be taken if you want to attempt a similar repair. If mishandled, mains electricity can kill you!
Step 2: Diagnose the Problem
I had this LED light mounted in my home and it recently stopped working after a problem I had with a loose ground wire. I already replaced it with a new one but I wanted to see if I can repair this one and use it in my workshop.
Step 3: Try Your Fix
After I removed the leads from the old resistor I’ve inserted the new pair through the same holes and without further inspection I was eager to try the lamp out. I connected it with some jump leads to a mains plug, making sure to isolate all of the jump wires connections for safety.
Step 4: Diagnose and Fix - Again!
I removed the light from the mains connection and continued with further inspection. What caught my attention is this smoothing capacitor that was across the input on the bridge rectifier as it had some discoloration. I removed it from the board and sure enough, the capacitor had a crack on one of its sides.
Step 5: Success!
Sure enough, I had a success. The light started working and even though it looks flickery on camera it produces a nice light in person. I then set to isolate the driver board and proceeded with assembling it back to its case.
Why do outdoor LED lights fail?
There are two different metals inside the LED light fixture - the socket contact and the LED lead. When exposed to water (and even oxygen, from which the air we breathe consists), these materials can undergo a chemical reaction that causes corrosion and finally failure of the light bulb. Luckily it's easy to enhance the waterproof characteristics of an outdoor lighting by using some dielectric grease. It will stop the humidity and air from getting into the LED light and consequently prevent the corrosion.
What happens if one bulb is not working?
If the one bulb is not working the whole string fails, so the failed light usually cannot be detected. Thus you'll need to pull out each bulb and successively insert a new one in its place until you find the failed one. Read the user's manual before doing this. Sometimes you may detect the stuck caps.
Can water get into LED lights?
In the USA, Canada and most of Europe winter is usually very damp, so the water can get into lighting fixtures. LED outdoor lights are supposed to be sealed, but the assembling is not always perfect.

Can you replace a string light if it fails?
When it comes to LED string lights, it is vital to detect the failed light and replace it as soon as possible. There are two main ways of making string lights - in first case failed bulb will stop the work of the whole string, and in second case the string will still be working but the rest of LED bulbs will be under the higher voltage which may cause additional failures.
Introduction
If your LED light strips are malfunctioning, then this guide may be what you need. Light strips malfunction when there is a faulty connection or wiring between two sections of the strips. These faulty connections can hinder the power flow and deactivate other working strips that are connected to the faulty strip.
Step 1 How to Repair LED Strip Lights
Find the spot where the lights stop working and where there are four connections labeled in descending order, "12V, R, G, B" with a scissor "cut here" marking and a copper colored backing.
Step 2
With a scissor, cut along the "cut here" line, separating the faulty strip from the working strip.
Step 3
Align the new strip next to the working strip and keep them steady. Look at the four connections like a mirror image. R to R, G to G, and so on and so forth. Apply solder in any order for all four connections. Make sure solder is secured and steady.
Step 4
A solder and soldering iron are fairly common and easy to acquire at a hardware store. Extra length of lights may be left over from initial use, use these first before buying more in order to lower costs. In order to put the lights back where they originally were, some form of an adhesive agent may need to be utilized.
