LED car headlights

Due to their shape’s versatility and ability to offer even stronger advantages, LED headlights are increasingly being included as standard equipment on many modern automobiles.

LED car headlights

This feature is not available in earlier model years. However, installation kits are available that may be installed even if you have little to no expertise working with mechanics, even if the manufacturer has not provided for the installation of LED headlamps.

These kits can be purchased online. In this article, we will explain what factors you need to consider when installing new lighting, as well as what factors you need to consider when shopping for lighting.

Why should the lighting be changed?

The “Light Emitting Diode” (LED (light-emitting diode) is a type of lighting that, in comparison to its predecessor, the light bulb, and its direct competitor, the xenon headlight, possesses several benefits that apply not only to drivers but also to passengers and other people who use roads.

To begin with, they are significantly more long-lasting, having a service life of tens of thousands of operating hours. Thanks to their high efficiency, they use less electricity while producing the same amount of light as traditional light bulbs.

The installation will especially be appreciated by the traffic approaching from the front.

Due to the fact that the light that LED headlamps emit is emitted from a variety of sources, they have substantially less glare than traditional headlamps. Even with the high beams on, other drivers won’t be too bothered.

LED headlamps with multiple beams, manufactured by Mercedes-Benz and Audi’s Matrix LED headlamps, can be seen here.

Proceed forward by one step

These incredibly unique LED headlamps represent a step forward in technological development compared to standard LED headlamps.

A computer in communication with a tiny camera can control each of the 36 LED modules individually.

This makes it possible, for instance, to recognize traffic circles and adjust the lighting directly or to dim the high beam when oncoming traffic is ahead.

It also makes it possible to recognize pedestrian crossings and adjust the lighting accordingly. Currently, the most advanced versions of this equipment are the only ones that can support these systems.

There is a possibility that within the next few years, there will also be the opportunity to retrofit devices such as these.

One minor drawback is the relatively high cost of acquisition. Even though LEDs last substantially longer than ordinary lights that employ H3 bulb holders or xenon bulbs, their purchasing price is still significantly greater.

The fact that LED lights produce a significantly lower amount of waste heat is both an advantage and a potential source of problems.

For instance, moisture that makes its way into the headlamp and clouds might not evaporate as quickly as it usually would.

However, if adequate care is taken to waterproof the area, this will not be a significant problem. Pulsed LED light is perceived by a tiny percentage of people as resembling a string of pearls.

This is because LED lights tend to turn on and off quickly due to their short run times and pulsing frequency.

As a result, this issue has arisen. This can be very unsettling; however, manufacturers typically reduce the severity of this effect by applying technical safeguards.

Requirements and other consideration

The use of headlights as a safety device is demonstrated during the day and the night.

The vehicle’s interior can be roughly categorized into three “zones”: the front, the side, and the rear.

The following are the regulations that must be followed regarding color and characteristics:

Front steering

– White should be the color of all other lights, except for the fog lights and the indicator for the direction.

-The following lights must always be present: reversing lights, high beam, low beam, parking light, reflector, and high beam.

-Clearance lamps, daytime running lights, and fog lamps can be selected as options

Side direction

It is required that all lights produce an orange or yellow glow.

The following lights must always be present: Indicators of direction and a flashing light for danger.

-Side marker lights and reflectors are not required but can be added if desired.

The following is in the reverse direction

– Different hues are utilized depending on the sort of light that is present.

-White is the color that must be used for the required reversing light.

-The required turn signal should produce a light that is yellowish-orange in color.

-Red is the color that must be used for the obligatory taillight, brake lights, and parking light.

-The rear fog light, which is red, and the reflector are both optional (red)

In terms of regulations concerning brightness, there are no specific values for LED lights; these regulations only apply to traditional bulbs.

The H8 model can produce approximately 800 lumens, while an H1 bulb has the potential to produce up to 1,150 lumens.

Nevertheless, it is essential that the low beam offers sufficient illumination that is free from glare, and that the high beam offers sufficient illumination overall.

The information on the luminous flux is secondary, given that other headlamps, such as xenon headlamps, can achieve significantly higher values.

Naturally, it is also possible to create your very own LED headlamps, as well as the housing for them, and install the whole thing in your own vehicle.

However, after that, you would be required to go to either the MOT or the DEKRA in order to check whether or not the legal regulations have been followed. Even if you just purchase and install the LED headlights, this is something that would be required in principle.

There are, however, two certification marks that guarantee that this component, when combined with the specified vehicle, complies with all legal directives and regulations.

Installation, is generally quite simple

In theory, there are two ways to acquire LED headlamps: purchasing an assembly set or utilizing LED headlamps that are intended for replacement purposes.

In the first possible configuration, the headlights and housing are both entirely replaced at the same time.

In most cases, this is not a problem, and the entire process, including disassembly, takes no more than an hour per side.

However, the devil is in the details, and it is very important to make sure that the headlights are completely waterproof so that there is no chance of rainwater getting inside them.

In addition to this, one must pay careful attention to the wiring.

LED headlights require a current that is rectified and pulsating. In many cases, the power supply of larger vehicles is not compatible with LED lights; as a result, adapter parts or transformers must be installed.

This is especially common with larger vehicles. The description of the product will typically include this information.

If it is only an upgrade for your vehicle, for which LED headlights are theoretically already available, but are not intended for the model in question (for example, the Golf VII), then the necessary technology is already installed, and all that needs to be done is the housing and plugs to be replaced.

When it comes to LED headlamps, the housing should be left alone; however, conventional bulbs should be switched out for LED alternatives.

These either directly combat the old power supply systems or come with adapter pieces that directly combat the old sockets.

Alternatively, they are directly compatible with both. Because the assembly is so similar to changing a regular bulb, there is a nearly nonexistent chance of making a mistake during the process.

This is not always the case, however, as there are also LED replacement headlamps that have active cooling, such as a fan, for example, which also requires electricity to operate.

If the installation instructions provided by the manufacturer are followed to the letter, you shouldn’t run into any issues.

Adjusting the headlights (both angel and devil’s eyes)

Within the realm of tuning, a trend has taken hold that now also makes use of the benefits that can be realized through the application of LED technology.

The unique shape of these daytime running lights is sometimes referred to as “angel eyes,” but they can also be called “devil eyes” for a more sinister take.

Because they are less important to the overall safety of the vehicle, daytime running lights are not as strictly controlled as low beam or high beam, for example.

Therefore, it is feasible to deviate from the standard design to a greater extent, which is something that is also done.

Angel’s eyes appear as if two glowing rings surround the low beams, as well as the turn signals and brake lights.

The eyes of the devil are accomplished by using a curved edge, which, as a result of the angle at which they are positioned, creates the illusion that the car is giving someone an evil look.

Eye Devil’s and angel lights in white are also easily mountable and legal to use while driving; however, colorful versions, which are widely sold online, are not.

Due to the fact that this change will affect safety-critical components, either an ABE or ECE operating permit will need to be obtained, or the components will need to be presented to the appropriate authorities.

A concise rundown of everything you need to know about LED headlights

What are the benefits of using them?

– A significantly increased average lifespan

– The exact amount of light output while using significantly less electricity

– Less glare

Exist any potential drawbacks as well?

  • A high price to be paid for acquisition

– Some degree of compatibility issues with the previous voltage supply system

– The string of pearls’ effect

What are some of the challenges associated with retrofitting?

Those who purchase a retrofit set are required to replace not only the light medium but also the entire housing of the device. Pay close attention to the positioning and ensure that it is completely waterproof.

The housing for the headlights is made to stay on the vehicle after LED headlamp installation.

The power supply system is frequently already compatible with LED headlights if they are currently offered for the specific type of automobile in question.

In most cases, an adapter or transformer is necessary in order to operate older models.
In any case, you must adhere to the manufacturer’s installation instructions exactly.

Attending a workshop is highly recommended for anyone who has any questions.
