So I just finished replacing the halogen headlights on my 2500 Custom with the LTZ/High Country OEM LED assembly.   I found a set on eBay, and then purchased a plug-and-play harness adapter from Gen5d

Give it some time and expect to spend some money. I see 3 options being the available in the future.   1. Morimoto will probably make some aftermarket LED housings that are direct swap and p

Hi everyone, I installed my LED headlights on my 2020 Silverado HD Custom, I purchased my headlights from a guy outside ebay but he was offering the headlights on ebay originally, I order the harness

Well gang, all I can say, is wow!

It's night and day difference.  

Ya know, one of the best things about my 2019 1500 Silverado were the LED Headlights.  And, once ya have them, it's just torture to go back to halogens lol

At any rate, really glad and lucky to find such a great set available on Ebay. This set was flawless. Not a scratch on them.

      LED headlight bulbs  become the best replacement for the factory halogen bulbs. However, when choosing and replacing the LEDheadlight bulbs, you will find some problems.
      Why Choosing LED Headlight Bulbs?
      LED headlight bulbs are known to offer more benefits as compared to other standard bulbs. LED headlights are widely used to upgrade halogen bulbs in vehicles. LED headlight bulbs are known to be highly energy efficient. They use less power to produce the same amount of light output as halogen bulbs. LED headlight bulbs consume less than 60% of the total energy required to power a halogen bulb. This means your car will need less fuel to run the alternator. In addition, using LED saves power for other electrical devices such as the stereo and phone.
      LED headlight bulbs also have a longer lifetime as compared to halogen bulbs. If they are supplied with the right amount of power, they offer at least 20,000 working hours. This saves your money since you don’t have to replace them regularly.
      These headlight bulbs also have an outstanding optical performance. You can easily control the direction of the light to maximize visibility. This allows you to direct the beam of light at a low angle to avoid causing glare or blinding the drivers in oncoming vehicles.
      Vehicles with LED headlight bulbs produce a brighter beam of light than halogen bulbs. This gives you move visibility especially at night and during bad weather such as snow. Better visibility enables the driver to make proper judgment and avoid unnecessary accidents.
      The LED headlight bulbs are also easy to install. You can buy and an LED retrofit-kit which allows you to replace the halogen bulbs in a few steps. The bulb doesn’t require any modification in the wiring of your headlights and it doesn’t affect the performance of other electrical components.
      How to Fix the Problems When Upgrading The Headlights?
      It is easy to upgrade your headlights with LED headlight bulbs. However, you can encounter various problems if you don’t use the right LED headlight bulbs. Low-quality LED bulbs have poor performance and they can cause some safety issues. Some cheap bulbs are not designed with safety in mind and you will notice that some of them produce an extremely bright light beam. Strong light causes glare and makes it difficult for other drivers to see. Such LEDs can cause eye problems and even accidents at night.
      LED headlight bulbs are known to produce less heat but they can also overheat when used for a long period of time. Some low-cost LED bulbs lack small fans and heat sinks for heat dissipation. Such bulbs should not be used in headlights since they can overheat and fail after some time.
      Flicker or Dashboard Warning?
      When you install LED headlights on vehicles without Canbus, they will work perfectly without adding any additional driver. However, you can experience some problems if your vehicle uses a Canbus (Controller Area Network Bus). Canbus checks the electrical components of your vehicle and sends their status to the control unit. You might encounter problems such as dashboard error that notifies you that the bulb is out, flickering of the headlights, bulbs not lighting up or even low light beam. Therefore, it is advisable to check if your vehicle has Canbus before upgrading any electrical component. But it is easy to fix these problems. Just buy an appropriate Canbus Driver for your vehicle and install it after replacing the bulb.
      It is advisable to use some LED bulbs series such as the T1 and W series since they come with Canbus drivers. These bulbs series are a better option when it comes to replacing halogen bulbs with LED headlights, and you do not know if your car is equipped with the Canbus system.
      Check the Factory Bulb Type But Still Cannot Put The New One In?
      Before you buy led bulbs, you have to check your car manual or ask an expert so that you can select the right bulb type. However, some LED headlight bulbs cannot be 100% installed in some vehicles even if you choose correct bulbs with the right plug-type fitting. Vehicles such as BMW, Audi, Mercedes-Ben, Volkswagen, Buick, Hyundai, and others that needs H7 led bulb for high beam or low beam need to use the special bulb holder. If the factory H7 bulbs have the bulb holders, you can use them on the new LED headlight bulbs. But some factory bulbs and bulb holders are fixed together. So you may need to purchase the bulb holders according to your vehicle type.
      Fortunately, Auxbeam provides you with H7 LED bulb holders that can allow you to fit LED headlight bulbs in these vehicles. Auxbeam has got every H7 LED bulb holder ready for you to choose. After you have purchased the LED headlight bulbs and the H7 led bulb holders, you should make the right connections on the terminals to avoid damaging the headlights.
      The Factory Dust Cover Cannot Fit In.
      Dust cover is an important item in the headlights since it prevents dust from getting into the bulbs. Dust can hinder heat dissipation and make the bulbs to fail. You can buy the right LED headlight bulbs but discover that the installation process cannot be completed since the cover cannot be reinstalled. Some LED headlights are usually designed with a bigger heatsink. The heat sink occupies most space and it doesn’t allow the rubber dust cap to be reinstalled.
      You can also get an LED headlight with a massive fan which occupies more space. The big fan gets too close to the dust cover and this prevents it from getting sufficient airflow. This hinders the fan from functioning properly and the bulb can get too hot and fail prematurely.
      Some people try to solve these problems by drilling a hole on the dust cover and trimming some parts to accommodate the massive heat sink. However, this is a bad approach since it is time-consuming and you can accidentally damage some components.
      All the components of an LED are important and there is no way you can remove the big heat sink or fan from the bulb. These components provide cooling which determines the durability and light stability of the bulb. In addition, the headlights require a dust cover and you can’t do away with it if you want your bulbs to last for a long period of time.
      You can choose Auxbeam T1 series or A2 LED headlight bulbs. They are designed in small bulb size. Thus, you dust cover will fit in. The reliable solution is to use the Auxbeam headlight dust cover which fits perfectly in all types of vehicles. This dust cover accommodates LED headlights with large heat sinks or large fans for cooling the bulb.
      There are many different situations why the LED headlight bulbs do not be installed and work normally. Sometimes, it is not the LED headlight bulbs have some problems. There are some little problems and accessories you also need for your vehicles. If you want to know some other problems that do not mention here, you can tell us and we will try to help you fix that. If you want to know more about LED lighting and vehicle modified parts, please read on to know more.

      Faulty headlights are one of the things to blame for accidents on the road. Thus, for you to stay away from road accidents or get pulled over by traffic enforcers, you should see to it that your car’s headlight bulbs are in good working order.
      It’s advisable that you do regular maintenance or changing of your headlight bulbs. There are indications to look out for when your headlight bulbs are not in excellent working condition.
      The Importance of Headlight
      Ford Headlight Bulbs
      Headlights are an essential part of any vehicle because they ensure safety when you’re driving on the road. They make sure that you see the road clearly and for other motorists, as well as pedestrians, to see you.
      Your car headlight bulbs also provide you with good visibility to see if there are any hazards such as a slippery road or road blockage. It might sound understandable, but some people still fail to take into account the importance of headlights.
      Common Headlight Problems

      One of the most common issues of car headlights is a broken switch. In this case, you’ll have difficulty switching between headlight modes. The lights may come on and off or may have problems on how a particular mode do its function.
      Another obvious sign of faulty headlight bulbs is if they only provide dim illumination or they don’t turn on at all. Problems in your car headlights are safety hazards that you need to take seriously and find solutions.
      Halogen vs. HID vs. LED Headlight Bulbs

      There are different types of headlight bulbs that you can find in the market today. It’s crucial that you know about them so that you’ll have the best buy. Read on below for a comparison between the common types of headlight bulbs: LED, Halogen, and HID.
        Halogen Headlights HID Headlights LED Headlights Advantages  
      Easy to Replace
      Use Less Power
      Brighter Light
      Longer Lifespan
      Doesn’t Have Strong Glare like HID
      Disadvantages Energy Intensive  
      Prone to Overheating
      Extra Sensitive
      Strong Glare  
      More Expensive than Halogen
      More Expensive  
      Difficult to Fit
      Halogen Headlight Bulbs
      High Beam
      Halogen light is an advanced form of incandescent light. It’s composed of a combination of nitrogen and argon gases that are contained within a heat-resistant package that also has tungsten filament.
      From the car’s battery, the electrical charge is delivered to the tungsten filament, which then heats at around 2,500 degrees Celsius to create light. This procedure is called the incandescence process.
      HID Headlight Bulbs

      For almost two decades, the halogen bulb went without a rival as the standard headlight bulbs for vehicles. However, when the HID or high-intensity discharge lamp came, the dominance of halogen bulbs was threatened.
      HID bulbs use xenon gas to start its illumination process. People often preferred it over halogen bulbs because of its high-intensity light and color temperature.
      HID lights have the same function as neon lights. The electrical charge passes through a gas-filled tube with electrodes at both endpoints. Then, the opposite electrodes stimulate the halide salts and xenon gas contained in a quartz enclosure to create illumination.
      LED Headlight Bulbs
      LED or light-emitting diode differs widely from all the headlights mentioned when it comes to its lighting process. In LED headlight bulbs, negative electrons pass through holes in a semiconductor to generate light. When electrons enter a low-energy hole, there will be a release of photons.
      This method is called electroluminescence process that occurs at a frequency of a thousand times per second.
      Difference Between Low Beam & High Beam
      T1 headlight bulbs
      In most vehicles, there are what you call low-beam and high-beam headlights. It’s a must that you know about what are the purpose and functions of both for you to use your lights properly.
      A low beam is also called a passing beam or dipped beam. It provides limited light so that it does not dazzle other oncoming motorists. Drivers switch on to low beam, especially if there are other vehicles on the road.
      A low beam headlight is directed either sideward or downward to provide road visibility with less glare at night.
      High beam is also called full beam and main beam. The high beam provides bright light to maximize the distance of visibility of the driver.
      When the high beam is on, its light is directed in front of the road. When one is in the middle of the road, the other oncoming vehicles may not see that people and accident may happen, because of the high beam you turned on. That is because the intense high beam will glare the oncoming vehicles. It’s not suitable to use high beam when there are other vehicles and people on the road. That’s why you should take care when using high beam because it can dazzle other motorist and can cause accidents.
      How to Adjust Your Car Headlights
      There are times that your car headlights are misaligned, thereby not providing the illumination that you want when you’re driving on the road. Therefore, it’s advisable that you know how to adjust it so that you will prevent accidents.
      Follow the Steps:
      Step 1: Level Your Car
      The first step to do when adjusting your car headlight is to remove any extra weight from your car trunk. You should
      also make sure that the tires are leveled on the ground. Then, you can check if the headlight aim is at the zero position.
      Step 2: Position Your Car
      Next is to position your car on a level ground ten to fifteen feet from a-dark wall. You should ensure that the front of the car is directed to the wall. You can do it in a paved driveway or a level parking lot for that purpose.
      Step 3: Turn the-Headlights On
      Mark the vertical and horizontal center lines of the headlight-beams with masking tape to create two T’s on the wall. In this stage, avoid using high beam or fog lights.
      Step 4: Ensure the Lights-are Level
      Use a carpenters level between the two marked lines to determine if they’re level. If they’re not-even, use-a steel tape to measure the distance of the lower mark if it goes much higher up the wall and lowers it to attain the same height as the other marker. Both center lines should not go beyond 3.5 feet from the ground.
      Step 5: Adjust the Lights
      Put the car on the reverse, 25 feet away from the wall. It’s a must to use a tape measure to know the distance from the wall. Then, turn off the lights. Get rid of the trim ring and find the adjusters. After that, adjust the vertical and horizontal screws, and see if the light is leveled on the marker on the wall.
      Adjust headlight bulbs
      In Conclusion
      The headlight is an essential part of your car. Thus, you should know how to properly use them and do regular maintenance and adjusting to prevent accidents on the road. You can take some knowledge from this article on how to make the best use of your car headlights. Also, we have different blogs about lighting and vehicle modifications, if you are interested, please read on.
