Audi’s laser headlights, in contrast to conventional headlights or even LED lights, which employ bulbs and diodes, respectively, literally use a laser and direct its beam through a phosphor converter. This generates light at 5,500 kelvin, which is extremely white and almost blue in color.

Why would an Audi have laser headlights?
For a while, the large A8 sedan served as Audi’s flagship. It’s also frequently the company’s technological leader, whether it’s a feature to pamper, assist with navigation, or keep drivers out of trouble.
The 2019 Audi A8 is now aiding in the start of a new age in lighting. The latest in high-illumination, low-energy technology is used in the car’s optional LED Matrix headlights. Additionally, they offer a striking characteristic look to the front of the car.
Additionally, they have a great new technological advance called laser high beams. The Audi can better illuminate dark roads with these. One minor issue: Audi is unable to obtain authorization from American regulators to activate them. Many of the brand-new automobiles that buyers have in their possession already have the hardware, but the software has been delayed pending regulatory approval.
The Matrix LED headlights are already quite effective at illuminating a dark road in the meantime. Once the laser lights receive approval, we’ll have to wait and see how they perform.
The development of headlight technology over the past several decades is undeniable, and according to safety experts, greater lighting can improve drivers’ visibility on dark roads, including their ability to notice pedestrians, cyclists, and animals.
However, because other drivers frequently have a negative attitude toward being dazzled by them, excessively bright and improperly focused headlights are becoming a bigger issue. The Audi LED Matrix lights have an intriguing ability to automatically change the beam when they detect an approaching vehicle in order to avoid shining onto vehicles traveling in the opposite direction.
But headlights that are too dim are another issue that is getting worse. The plastic headlight lenses on older cars may become clouded and yellow, reducing the output. According to research, even in vehicles that are just three to five years old, deterioration can be seen. Many vehicles between 10 and 15 years old may have lenses that are seriously damaged.
When compared to brand-new headlights, the degraded headlights only provide roughly 20% of the overall light output, according to Megan McKernan, manager of the Auto Club’s Automotive Research Center in Los Angeles.
The lenses should be changed, ideally with brand-new ones from the car’s manufacturer. Independently produced aftermarket lenses provide an option that is almost as excellent. Both of those options can be expensive, not to mention the cost of hiring a qualified shop to take out the old lenses and put in the new ones.
According to Megan McKernan of the Auto Club, “it will enhance the light output to roughly 70% of new headlights.”
Yes, it’s crucial to see where you’re going and be seen. Some of the latest safety technology, like laser headlights, advances very old safety technology as it makes its way into new automobiles.
Are laser headlights preferable to LED ones?
In the last few years, the incandescent, halogen, and LED headlights of the past have all seen considerable changes. This is even further enhanced by laser headlights, which were first used on the BMW i8. They emit a brilliant white light that illuminates the road in front of you.
According to BMW, laser headlights can provide up to 1,000 times more light than an LED while using a lot less energy. Additionally, they may illuminate the road up to six times as much as conventional LED low beams, greatly improving visibility.
How do laser headlights work?
First of all, keep in mind that laser headlights do not actually direct laser beams onto the road in front of you. Instead, a system of mirrors receives the beams from three blue lasers. The energy is then concentrated by the mirrors into a lens made of yellow phosphorus, which emits a bright white light. Direct eye contact with the light that these beams reflect is secure.
Are laser headlights worth the cost?
Due to a 1968 law banning high beams that cannot be manually turned down, US officials are still unwilling to permit the widespread use of laser headlights. To rate the safety of specific vehicles, the Insurance Institute for Highway Safety is contemplating including headlamp technology. If they do, this might accelerate the adoption of several lighting innovations, such as laser headlights.

How do laser headlights work?
Although recent developments in LED technology have generated a lot of noise, light technology isn’t just evolving in this field. Reading CDs and Blu-rays, sci-fi ray guns, and occasionally amusing online movies have all made use of laser technology. To improve headlight visibility and performance, laser light is being used in automotive headlights. Many consumers are now left inquiring about the efficacy, safety, and energy efficiency of laser headlights, particularly in more recent hybrid vehicles.
So how do they function? Three tiny blue lasers that are directed at a row of mirrors in front of the headlight assembly are how laser headlights work. The mirrors concentrate the laser light into a phosphor-filled lens. When ignited by the blue laser, yellow phosphorus produces a bright white light. The white light shines onto a reflector, which reflects it out the front of the headlamp after diffusing it. A strong beam of light is produced through reflection and diffusion that is yet safe for other drivers’ eyes.
According to early reports, laser lamps are approximately 1000 times brighter than LEDs (a shocking claim considering how LEDs have been taking over the automotive lighting market). If confirmed, laser headlights would be even more compact than LEDs because the technology required to make them are currently more compact than traditional LED ones. As a result, there is more area under the hood for engine power to be increased or a more aerodynamic body to be built.
Current laser lamp versions also consume around half as much energy as LED headlights when it comes to energy usage, making them an excellent option for electric or hybrid vehicles. This implies that hybrid or electric vehicles will be able to travel farther while using less battery power and having brighter headlights. A lot of these headlamp systems can also be used in conjunction with GPS information and infrared sensors to guide headlights around turns. Headlights will be able to detect people, animals, or other things on the road and warn drivers in advance thanks to the integration of sensors.
When will they be offered on cars made for the general public? There are now only two German cars with restricted manufacturing that use laser headlights in Europe. Due to a dated federal legislation that only allows for high beam and low beam options for automobile headlights, it might be some time before we see them here. The National Highway Traffic Safety Administration (NHTSA) will need to revise the regulations before laser headlights are permitted on American roads. It will eventually be approved and used on regular production cars because of its benefits, which cannot be denied.
How do laser headlights function?
When you hear the words “laser headlights,” the first thing that comes to mind is an automobile with laser beams shooting from the front. Coherent monochromatic light beams would undoubtedly provide poor illumination outside of a very small area that is located a great distance away. Fortunately, laser headlights don’t operate in this manner at all.
Instead, solid state laser diodes positioned inside the headlight make up laser headlights. These blue lasers are directed at a yellow phosphor that resembles the white LED phosphor. The result is a strong, brilliant white light that can be reflected off of reflectors and sent out of the headlights in the direction of the road. This method of creating laser headlights has various advantages. Compared to LEDs that produce the same amount of light, they use less energy and take up less space.
As a relatively new technology, laser headlights are now only found in a small number of BMW, Audi, and other high-end vehicles. BMW’s technology was created in collaboration with lighting industry leaders OSRAM. In actual use, a standard LED low-beam lamp is employed, and the laser is used to produce a high-beam that is exceptionally bright and focussed. This has a 600 meter illuminating range, which is twice as far as traditional LED high beams. The projector-grade indium gallium nitride diode lasers that are employed in the lights have a power rating greater than 1 watt. The requirement for such technology to function at severe temperatures is one of the difficulties in applying it in an automobile context. Automotive lighting must be able to tolerate temperatures ranging from 40 below zero to 50 degrees Celsius, while research lasers and laser pointers may generally only be used at standard room temperatures. Fortunately, the laser’s high efficiency means that it doesn’t produce a lot of heat on its own to make matters more difficult. Adapting the optical package for the demanding, highly vibratory environment prevalent in the automotive application presents additional engineering problems. As with any such device, it’s crucial to make sure that, in the unlikely case of an accident or malfunction, the end user cannot be exposed to hazardous laser radiation.
The value of Audi’s laser headlights
Editor Ollie Marriage discusses how the laser lights are able to illuminate a road far more effectively than conventional lights in this new long-term update for Top Gear’s Audi e-tron GT. He even goes as far as to say that they are well worth the upgrade.
In the US, are laser headlights legal?
Adaptive headlights are now officially permitted according to the infrastructure bill, which was enacted in November 2021.
Even though there is 60% less traffic on the highways at night, more than 40% of deadly car accidents still happen. Furthermore, compared to vehicles with headlights that receive a poor grade in the Insurance Institute for Highway Safety’s headlight rating program, vehicles with good-rated headlights had nighttime crash rates per mile that are approximately 20% lower.
Given these results, it is difficult to conceive that lawmakers would not take every possible measure to lower the rate of accidents that occur at night by promoting the use of cutting-edge lighting systems. However, while some technologies, such automatic high beams, have received legislative approval, adaptable headlights, also known as LED matrix headlights, have not.
Intelligently reacting headlights are known as adaptive headlights. They want to give drivers more visibility and time to respond to upcoming situations. A 2015 study from Sweden that demonstrated adaptive headlights (ADHLs) dramatically reduced single-vehicle passenger car injury collisions in the dark by 39 percent served as a testament to the technology’s effectiveness.
However, despite numerous reports attesting to their worth, ADHLs remained illegal in the United States until President Joe Biden signed the infrastructure bill into law in November 2021.
Which automobiles have laser headlights?
Even though the BMW i8, BMW 7 series, and Audi R8 LMX are the first vehicles featuring laser headlights, the lights are still fairly hard to come by because they are still a relatively new technology, particularly in the US market. SLD has developed a kind of workaround for the domestic market while trying to persuade American regulators to change their car lighting regulations. According to Shuji Nakamura, “We are working on a high-beam boost, where laser lights can be added to the current high-beam headlights in an automobile.
I think it’s only a matter of time before the lights are included on every new vehicle with replacements for DIY enthusiasts who would like to try out a laser headlight conversion. After all, with such ingenuity, the laser is still four times brighter than a conventional LED headlight.
Which lamps are ideal for driving at night?
Even for good-quality bulbs, upgrading your halogen headlights to bulbs with a high light output can prove to be a considerable improvement for a relatively moderate cost. No of their level of experience, all drivers may experience anxiety when operating a vehicle in low light.
A more recent set of headlights could do the work, but it’s crucial that the automobile or truck being driven is well-equipped with various safety features. It is probably time for an upgrade if the headlights being utilized right now are halogen lights with low beams or even beams that are nowhere near as brilliant as they should be.
Before Changing the Bulbs
Even if the headlight warning light hasn’t turned on, it is recommended to clean the existing headlight housing on a car and look at what is already there before you start looking through our list of headlight bulbs. A headlight restoration may be required if the casing is damaged. The front lens of a headlight must be clear and undistorted in order to get the most light and visibility out of it.
Headlight Bulb Considerations
Many lights also appeal to drivers due to certain design features, such as blue tints or xenon light characteristics. Many of our reviewers gave the headlights on the list of the best headlights below high marks for both their aesthetics and safety features.
Headlight protectants
Additionally, there are additional goods marketed as “headlight protectants.” These provide a layer of defense against potential UV deterioration and scrapes. A future restoration project may take longer if a product like this is used with one of our recommended headlights.
Bulb options
Customers choose LED lights and HID lights above all other types of headlight bulbs. HID lights, sometimes referred to as xenon headlights, operate by fusing xenon gas with electrical charge. They are well renowned for producing a brighter light than other bulbs and for having a lengthy lifespan.
Halogen gas is sprayed over a heated filament in LED headlight bulbs to produce light. It emits a clear, brilliant, and glowing light. Compared to halogen headlight bulbs, LED and HID headlights are both more expensive, but they also have a better reputation for lasting longer and being more effective in general.
Conversion kits
To upgrade the vehicle’s factory-installed halogen headlights to more effective and brighter LEDs or HIDs, you may want to consider a headlight conversion kit (a conversion kit will save you having to replace the whole of the assembly of the headlights).
Greater distance
In comparison to ordinary bulbs, LED and HID bulbs provide the best coverage and increase nighttime vision, especially in poorly lit locations and off-road situations where there is no available lighting.
Greater lifespan
Despite the lengthy lifespan of some lights, such as LED bulbs with LED chips, HID technology has the potential to be more energy-efficient. While an LED bulb can last up to 30,000 hours, a HID headlight can only last up to 10,000 hours.
