The most common problem with LED headlights is their flickering issue. This is the known fault with almost every brand of LED headlights. Hence, the manufacturers have made some technical changes in their LED headlights to resolve this problem.

Even if you are using the previous model LED headlights and facing the flickering issue, it is possible to get rid of it. Given below are some of the solutions that may help you to stop your LED headlights from flickering.

What Causes LED Headlights to Flicker

One of the major faults that cause the LED headlights to flicker is the lack of communication between the electric system of the LEDs and the computer system of the car. Another reason for flickering LED headlights is the irregular power supply. If you want to fix the problem, make sure to know its exact cause. It may take some time to identify the real fault, but you will be in a position to fix it. In some instances, you just have to add some additional parts to the electrical system of your car.

Most cars are still fitted with halogen lights. This suggests that the electrical system of these vehicles won’t support LEDs. When replacing halogen bulbs with LED headlights, you also need to change the response of your car’s electric system. The difference between your car’s computer system and the electronic frequency of the LED is what causes it to flicker. Since the electric system was designed to support the halogen lamp, it won’t work with the LED headlight.

How to Fix Flickering LED Headlights

You can fix the flickering issue of your LED headlight by taking into account various solutions. For instance, you can use LED decoders, load resistors, warning cancellers, and anti-flicker adaptors. Given below are some of the most authentic ways of how to fix flickering LED headlights.

Ensure Constant Supply of Current

The provision of an unstable current to the LED can prove fatal for your LED. This means you may damage it permanently if it continues to receive inconsistent power. Flickering is the sign that your LED isn’t getting the right amount of power.

You can typically resolve this issue by simply installing a driver with your LED headlights. It will allow the electric system to ensure a constant and steady supply of voltage to the LED headlight. On the other hand, you can use the LED headlight driver if the wiring of your car is too old.

Load resistor

This is another effective piece of equipment, which assists you while addressing the flickering issue. By using a load resister, you can provide the LEDs with a sufficient amount of current. When you switch from halogen to LED headlights, the power consumption decreases to a great extent.

With the help of a load resister, you can control the additional amount of current. As a result, the computer system of your car can communicate with the electrical system of your LED headlights. Usually, load resistors are easy to install, as you just need to plug and start using these gadgets.

LED decoder

Another efficient product that you can use to fix a flickering LED is an LED decoder. This particular component can store the electric current and release it stably and consistently.

A few car manufacturers use pulse power to light up halogen lamps. This technology helps reduce power consumption and the amount of heat produced by halogen bulbs. The provision of intermittent power doesn’t affect the overall performance of a halogen bulb.

On the contrary, when you want to replace your halogen lamps with LED headlights, you need to provide a constant supply of current. This is the area where you need an LED decoder. It offers a large capacitance and ensures a consistent supply of electric current.

Anti-flickering Adaptors and Warning Cancelers

The lack of communication between the car’s computer and LED headlights may cause the lights to flicker. In this situation, you need to purchase capacitors, warning cancellers, or anti-flicker adaptors. These devices serve as a translator and help the car’s computer to communicate with the LED headlights. It won’t read the flickering LEDs as the fault in your car’s electrical system. Furthermore, you also need to check the bulbs. Sometimes, bulbs aren’t fitted properly with their holders.

Moreover, you can also take advantage of an anti-flicker adaptor to resolve this problem. This is a tiny gadget but proves to be effective when dealing with different wiring issues. Installing an anti-flicker adaptor is easy and hassle-free. You just need to connect one end of this adaptor to the stock harness and the other end to the LED headlight. It serves as the easiest way to deal with the issue of flickering LED headlights. However, you need to purchase the right type of adaptor for your LED headlight. For this purpose, you need to match the model number mentioned on the LED headlight with that of the anti-flicker adaptor.
