How to Fix LED Flood Light Flashing On and Off – 2023 Guide

Flashing and flickering of the LED floodlights are the most common problem that almost everyone has faced at least once in life. And this is the only reason I have presented this helpful guide for you to fix LED floodlights that are flashing on and off and affecting the overall lighting of the home. This is an irritating inconvenience which, if it occurs occasionally, is acceptable but if it happens regularly is annoying.

This guide will take you to the perfect solution of fixing your LED flood light quickly with the help yourself. We will directly jump onto the causes and problems that can cause the LED light to flash because until and unless we learn the reasons, we will not understand the solutions of flashing correctly. Make sure to focus on throughout the article to learn both problems and solutions adequately.

We will be elaborating on the common problems and their possible solutions that you can perform on your own to solve the unnecessary flashing of LED floodlights.

Common Problems And Their Solutions

1. Loose Wire Connection

If the wire connection becomes loose between the bulb and the circuit, it is the top reason that can cause LED flood light flashing. This is because the current is affected when the wire is not correctly lined up. It may get hurdles and obstructions while reaching towards the bulb. You can quickly fix this problem by checking and maintaining the overall circuit program properly. Check for the breakage and folding of the wires to make sure that there is no disconnection or any hurdle in between the bulb and circuit.

2. Loosening Up Of The Bulbs

LED floodlights also flash if it is not fixed and tighten appropriately within the fixture system. This is almost similar to the problems mentioned above because it will also affect the current flow. Make sure to turn off the electrical supply from the primary circuit to avoid any electrical shocks before checking the loosening of bulbs.

Now what you can do to fix this loosening up of the bulbs is to tighten them up. Check for the fixture and bulbs connection and make sure they are tightened together. No bulb should be loose in its fixture. If this is the reason for the flashing of the light, it will be solved as soon as you tighten the bulbs.

3. High Wattage Appliances

This is a common problem that affects the power supply towards the LED floodlights. This results in flickering and flashing of the lights. If you have lots of high voltage appliances at home such as AC, electric heater, ovens, and refrigerators, and all of them are working together on one circuit, then there are chances, the LED flood light flashes on and off.

To solve this problem, you need to turn off the high voltage appliances in your home and check whether the light is still flickering or not. If the light is not blinking now, it means that this is the problem, and you can solve it by changing the primary circuit or dividing the main course into two circuits. Make sure to check properly for the problem and then go for the solution.

4. Breakage In Power Supply

Check for the watts you have in your LED floodlights at home. If you have >1000 watts of energy in the LED floodlights of your home, there are chances of flickering and flashing your LED floodlights because of the lower power supply. This problem can easily be solved by replacing LED floodlights. Make sure you get the lights compatible with your circuit and power supply so there would be no problems causing any flickering and flashing of the lights.

Why do LED floodlights to flash on and off?

Many reasons cause LED floodlights to flash on and off. The most common one is a disruption in the voltage of its circuit or the fluctuation in the overall circuit of the house. It is said to be the most fundamental problem but is easiest to solve.

Can you fix LED floodlights?

Yes, you can conveniently fix LED floodlights on your own. This is possible if you have all the accessories and tools with you. Further, you need to search for a good guide and step-by-step instructions to learn how to fix LED floodlights on your own. If you have zero knowledge of the fixation of LED floodlights, then you can take the help of a professional to avoid any problems.

Why do LED lights fail?

LED lights can fail if the temperature in the surrounding of these lights gets too hot and your light does not contain a heat sink in it. This will result in the overheating of the lamps that generally fail these LED lights. This is possible if you have used an LED lamp that is not compatible with its fixture.

How do you solve and fix the issue of LED flashing fast?

This problem can be fixed by the simple installation of a load resistor. You can minimize the speed of LED lights blinking to their original normal range. The resistors are correctly installed, such as they are fixed in parallel with each LED bulb located in the front and back.
