How to Install Led Headlights in a Car?

Whenever you buy a high-end vehicle, it'll likely come equipped with LED headlights as default, with some manufacturers preferring even more costly LED components over less effective halogen headlights.

However, you don't need to spend a lot of money on a premium automobile to benefit from what LEDs have to offer. Indeed, with LED headlight kits, any car can be upgraded with LED headlights without the requirement for a professional installation.

You, too, can gain from more efficient illumination and safer, more plainly visible driving with these headlights. All you need is a few simple skills and 30 min to 60 minutes of leisure time to install the LED headlights on your vehicle.

You don't need to be a technician to install these headlights in your own automobile, and they require very little technical knowledge. Here are the ways how to securely and successfully install LED headlights in a car for long-term usage.

What is LED Headlights

With each passing year, LED lights becoming more widespread - not only in automotive headlights, but in a wide variety of daily and industrial uses. 

LED lights differ from other types of lighting in that they generate their light electronically rather than relying on a filament or electrical charge.

As a result, they provide brighter light while emitting less heat, making them the lighting solution of preference for a variety of applications. LEDs have, of course, been limited in their adoption due to their high cost.

However, with LED headlamp kits becoming more affordable to drivers of all budgets, it is now easier than ever to acquire high-quality illumination for less money.

The Difference between Halogen and LED Headlights

Understanding the fundamental distinctions between LED and halogen headlights can assist you in making the best lighting upgrade selection for your car.

  • LED lights are often larger than the smaller halogen choices, which might complicate installation.
  • In any case, you'll be pleased with the increased brightness, lifespan, and performance of your new LED headlights over Halogen bulbs.
  • Halogen lights require a few seconds to warm up, but LED bulbs switch on instantaneously. LED lights to create a more concentrated, brighter light than the halogen alternatives.

LED Headlight Bulb Type

The following are two probable outcomes:

1) Single Beam Bulb - two separate bulbs are used for the high and low beams.

2) Dual Beam Bulb - This bulb combines the high and low beams into one.

Steps that Need to Be Followed

Make sure the car is parked inside the garage before proceeding. Working in the afternoon, especially a couple of hours before nightfall are ideal. You'll have enough natural light to do the task, and you'll be able to test the LED headlights in the dark without having to wait too long.

Step 1:

Before continuing, double-check that the automobile is placed within the garage. Start working particularly a few hours before sunset is perfect.

You will get sufficient amount of sunlight to complete the work. Also you don't have to wait much to check the LED bulbs in the nighttime. 

First, choose a light bulb that is the right size for the task. Ensure that the LED light bulb you choose matches your car's lights precisely. The bulb categorization is calculated by the type of your automobile.

It's essential to keep in mind that these light connectors are not convertible. Although an H3 and H4 light bulb offer similar light output, you can't be able to connect an H3 light bulb inside an H4 connector or the other way around.

Step 2:

Now detach the existing halogen light bulbs. The following is the standard procedure:

  • Pop up the bonnet.
  • Unplug the bulb from the power socket.
  • Remove the rubbery cover that keeps moisture out of the head bulbs compartment.
  • Loosen the spring which holds the bulb in place in the headlight compartment.
  • Carefully open the bulb.

Step 3:

  • LED lights should be installed! The LED package that you bought will include disc-shaped connectors that keep the light bulbs in correct hook, depending on the kind of bulb.
  • Simply plug in the adapter and place the LED light bulb inside. Now you need to flip the light bulb to better secure it in the compartment.

Step 4:

  • The tough phase is about to begin. Either a huge base or pairs of filament absorber plates at the base of the light bulb compartment will be included with the LED light bulbs.
  • You will not able to reattach the cover made of rubber as a result of this. You have two options: trim the clothing to create the opening larger or use another cover entirely.
  • It should be fit to the heat pipe such that it does not melt the covering when the light bulbs are turned on.  As we previously stated, the heat pipe will become quite hot after only a few minutes, so keep this in mind.
  • Extra rubber parts that stay beneath the hood may melt if the heat pipe becomes excessive hot. To guarantee a secured functioning, you need to so that the heat pipes are not in contact with sensitive components.
  • However, because of a shortage of flexible area beneath the bonnet, this will be more difficult to perform, so you should take as much time is needed as it’s your first time installing LED light bulbs.

Step 5:

  • The bulbs are being plugged in. This should be a straightforward play-plug approach. If you acquired the proper pair of LED light bulbs, all you have to do now is connect the wiring socket to your vehicle's factory system.

Step 6:

  • Check the light by turning on the headlights. You may now experience a more intense and brighter beam!

Step 7:

  • Task isn't finished yet. Perform a repeat check under the bonnet after testing the newly installed LED headlights to confirm all cabling and heat pipes.

Will LED Bulbs Melt the Headlight Assembly?

They won't become hot unless they're put incorrectly and the electronics casing touches plastic, but even then, the driver circuit might not get that hot.

Headlight reflectors, on the other hand, tend to reflect light from the sun onto the LED die directly owing to its shape. This can cause the LED to fail even if the light is turned on. If you're trying a refit, proceed with caution.

Maintaining and Replacing Your LEDs

If you utilize your headlights 100 percent of the time when driving, you may expect them to last up to 10 years.

This is a much higher driving time than halogen bulbs, which are projected to expire after approximately 5000 driving hours or fewer. Few drivers use their headlights all the time, and LED headlights may survive for over 20 years even at 50% utilization.

Frequently Asked Questions

Can you install LED headlights in any car?

Yes, you can install LED headlights in any car, but the light quality and color of the lights would differ from one car to another. A good rule of thumb is that if it works for your car, then it’ll work for any other car.

Can you just plug in LED headlights?

No, you cannot just plug in LED headlights. Your vehicle's headlights and brake lights must be wired properly to allow the headlight to operate independently from the other two.

This is a safety feature that prevents your car from having issues while driving. So, if you are planning on getting some LED headlights, make sure to check your vehicle's wiring first before ordering them.

Do you need a conversion kit to install LED headlights?

Most vehicles require a headlight conversion kit to be able to use LED headlights. This conversion kit allows you to convert your old bulbs to the new type.

If your vehicle has a standard headlight bulb socket, then you can easily get one, and this will allow you to switch to the LED bulbs without much hassle.

How do I convert my headlights to LED?

Most car headlights have a standard 120-volt AC outlet, which allows you to connect a standard lamp or light bulb. All you need to do is simply plug the lamp into the outlet, and the headlight bulbs will start working.

Can you just switch to LED headlights?

LED headlights are a lot better than traditional incandescent bulbs, but you can't just switch to them. The light emitted by these bulbs is not very bright, and they don't emit enough visible light to allow other vehicles to see them clearly.

For this reason, LED lights are only recommended for driving in the daytime, and when visibility is not a concern.

Can you replace halogen headlight bulbs with LED bulbs?

Yes, you can replace halogen headlight bulbs with LED bulbs. There are two main types of LED bulbs, namely, the tube-type and the bulb-type. While the tube-type is easy to install, they’re also prone to failure. On the other hand, the bulb-type is very reliable and long-lasting, and hence, they're often recommended for replacing halogen bulbs.

Can I put LED bulbs in halogen fittings?

LED bulbs don't fit in halogen fittings, but you can easily convert them to CFLs. To do this, you'll need to remove the halogen bulbs from the sockets and replace them with CFLs. Once done, you can easily install the halogen bulbs back in the sockets, and it should work fine.

Are aftermarket LED headlights legal?

Aftermarket LED headlights are technically illegal according to the Federal Motor Vehicle Safety Standard No. 218, but they can be sold with a waiver from the manufacturer.

However, some automakers might refuse to issue the waiver, and hence you might end up with a non-working aftermarket LED headlight. So, it’s always better to get them installed by a professional and ensure that they work right.

Do LED headlights draw less power?

LED headlights do indeed consume less energy than conventional halogen or HID headlamps. You can expect a reduction of about 30% or more when comparing an LED headlight with a conventional halogen lamp.

This is because LEDs use light-emitting diodes, which emit light much more efficiently than conventional halogens. Also, the intensity of light is far greater when using an LED headlight. These two factors help reduce energy consumption significantly, especially when the lights are not on.

Do LED lights get hot?

LED lights usually don’t get hot since they don’t consume much power. However, they should be placed away from a heat source, or exposed to direct sunlight to avoid overheating.

Are LED lights safe for cars?

Yes, LED lights are safe for cars. They are safer than regular light bulbs, as they don't contain mercury, which is hazardous to the environment. They also use less electricity and are a better choice over incandescent bulbs, which require about 1000 watts of electricity to run them.

Can I leave LED lights on all night?

Yes, you can leave LED lights on all night if you wish to. LED bulbs run much less energy than traditional light bulbs and are far more efficient than fluorescent lamps. However, LED bulbs don’t provide a warm glow and you might want to check whether the lighting is needed or not, so you should turn it off after a few hours or days.

What are the disadvantages of LED lights?

LED lights are great for their long life, minimal maintenance, low heat generation, and ease of use. They are widely used in a variety of household appliances and are a cost-effective replacement for traditional lighting. LED bulbs are also available in different colors, making them ideal for decorative purposes. 

However, they do have some drawbacks too. Most importantly, they use up less energy than traditional lighting options but are also much more expensive than fluorescent lamps. Another drawback is that LED bulbs are not dimmable, and hence you need to have a lot of them to brighten a room effectively. Also, LED lights are not suitable for some applications like ceiling fans.

Are LED headlights good in the rain?

LED headlights are better than halogen headlights in the rain. But they still have a problem with fogging which means that you need to make sure that your headlights are clean and free from moisture to avoid fogging.

Why do LED lights flicker in cold weather?

The flicker in LEDs in cold weather occurs due to a phenomenon called Schottky effect, and it happens when the voltage level of an LED becomes lower than the threshold voltage of its Schottky diode. 

To prevent this from happening, it's recommended to use an LED driver circuit, which can regulate the output voltage of the LED to provide a stable power to the LEDs. But if you're using a single LED, you can also use an RC snubber circuit, which works similar to a capacitor, to filter the voltage fluctuations of the AC mains supply.

Final note

The method of upgrading to LEDs is also similar to that of installing them but in reverse. It's just as simple to reverse the process, and if you install your LED headlights yourself, you'll be able to effortlessly change them when the time comes.

There is no special equipment necessary for the procedure, and many persons with no prior expertise may successfully install LED headlights. Installing your LED headlights should not be a problem, and the benefits of LED headlights over other types of bulbs make it a worthy investment.

Whether you are confident in your ability to install these lights yourself or require assistance, switching to more efficient, longer-lasting LED headlights will save you money in the long run.
