HOW IS THE LIGHTING PERFORMANCE OF AUTOMOTIVE LED BULBS?
A detailed look at the principle of LED lighting - Beam Pattern
Car lights are an important part of ensuring our safe driving in various environments in our daily driving process. With the development and perfection of automotive lighting technology, the requirements for automotive lights nowadays are not only in terms of brightness but also in terms of energy-saving and environmental protection, color, beam pattern display, and other comprehensive considerations. Today, we mainly talk about something related to beam pattern display.
Both LED and halogen bulbs work with reflectors. However, different reflectors have different internal structures. The exact actual beam pattern effect still needs to be tested whether it is a projector lens assembly or a reflector bowl assembly.
When it comes to the beam pattern we have to talk about the cohesion of light, take the more popular LED lights on the market, compared with the traditional halogen lights, it is clear that the LED are more difficult to gather light because the halogen bulb is lit by tungsten filament, the light source has only one central point, which is usually called "point light source", the light from the point light source through the reflection of the reflector bowl gathered together and spread evenly to the front, providing us with a sufficiently bright view.
● A halogen bulb is more similar to a "point-lighting" type function combined with a reflector.
● But LED bulbs have a facade body, the light is one-sided at about 140 degrees, also known as the "surface-lighting source".
WHY HALOGEN BULBS DO NOT SCATTER LIGHT WHILE LED BULBS DO? Since the luminous points of LED headlights and halogen headlights are different. A halogen bulb is more similar to a "point-lighting" type function combined with a reflector. But LED bulbs have a facade body, the light is one-sided at about 140 degrees, also known as the "surface-lighting source".
"Point light source" in the optics of the refraction angle and "surface light source" itself are different, "surface light source" is more likely to cause light scattering. "Point light source" in the optics of the refraction angle and "surface light source" itself are different, "surface light source" is may more likely to cause light scattering.
When you sit in the car, you will find that the road in front of you is bright and dark uneven, this phenomenon can be called BEAM PERFORMANCE BAD while when you stand outside the car where to look, the headlight effect is very bright. These scattering light bulbs are obviously not to be used.
HOW TO IMPROVE LED LIGHTING SCATTERING ON ANY REFLECTOR
Most LED chips are flat and square, and now the practice is to make the chips on the two sides as close as possible to achieve a point similar to 360-degree light. Thinning the center point is also the principle of the only concentrating technology at present. Almost allows upper directed ray to proceed without being interrupted AUXITO Q16 Series LED Forward Lighting:
AUXITO Y13 Series LED Forward Lighting:
Fitted with 1:1 beam pattern technology and ultra-thin 0.039in the baseboard, AUXITO LED bulbs concentrate beams that shine further down the road and will not blind oncoming vehicles with a clear cutoff line.
If the improper position bulb, then the light scattering does not focus which is not in the middle of the housing position, you will need to readjust the bulb position so that it is a 3-9 o'clock position which must be parallel to the arc in the reflector lens.
If the light beam is scattered - remove the bulb;
1) Loosen the set screw at the base of the bulb;
2) Adjust the base and bulb to the proper setting;
3) Tighten the set screw after adjusting;
4) Install the bulb in the headlight, and confirm the position of the bulb is parallel correct.
5) Check the light beam.
3. Choose high-quality LED bulbs as much as possible
A BETTER BEAM PATTERN - SAFE DRIVING LIFE!
AUXITO is trying to find who is willing to upgrade LED bulbs from stock headlight housings and what their opinions are on the results. I will offer free samples to you guys in exchange for an honest review.
If you guys are interested in getting some bulbs, please leave (the year/make/model) of your vehicle in the comment.
I appreciate all the love for AUXITO's LED bulbs, if you guys want to get free bulb samples please send me a private message directly or contact me through my email. Please do not leave messages on the AUXITO website, each of us has a different task, so please message me directly with any questions you may have. By the way, we only offer free LED bulbs to the first 12 people who contact me each month, First come, first served. Appreciate your consideration.

Reason: too many request
You first sentence is just an out right lie. And are your bulbs DOT approved?
LED's should never be used is a reflector housing. Anyone that drives at night (even day) knows which reflectors have LED's, the ones blinding you. This is just irresponsible advice.
You didn't even talk about the issue with LED's. Well lets start with how a halogen in a reflector works. It reflects the light in a beam and does have scatter light, there is no way around this (unless you put in a cut like a projector). So when you put in a LED, it will still scatter light, just much brighter light. This is the issue with LED's the brightness, not any other nonsense that was spewed.
Dont use LED's in reflectors and dont buy from companys that promote unsafe behavior.

Certified by DOT, does it matter?
Almost all LED lights on the market are not certified by DOT. You need to redefine the criteria for commenting on whether LED is hazardous.
I have sent quite a few LED headlights to Ford truck forum users and have not heard them complain about these problems.
Take, for example, the Department of Transportation (DOT) regulations for acceptable headlights. They aren’t anything one might not expect, and can be broken down into beam intensity, brightness, and color.
Intensity in this case refers to the prohibition of extremely bright or scattered lights that could temporarily blind pedestrians and oncoming drivers. Of course, this can lead to dangerous accidents, so it is a no-brainer that this is one of the regulatory factors for not just LEDs, but headlights in general.
Brightness is an important factor too, and depending on the state, your headlights have to illuminate a certain stretch of a dark road ahead of you. Most commonly, this number is 1000 ft, but it isn’t the same everywhere in the world. Basically, you have to be able to see a far enough distance ahead of you for your lights to be safe and acceptable.
Finally, there’s the question of color of the lights. Simply put, there are very few (if any) places that will let you have headlights of any color other than white or yellow. There are some LED-equipped headlights that emit a bluish-white hue that are technically legal, so there’s a bit of leeway in that regard. However, as a rule of thumb, they have to be similar enough in color to conventional headlights to avoid confusion on the road (for the driver and others around). That was a basic overview of the DOT regulations regarding headlights, with LEDs as no exception. There are other regulations surrounding headlights, depending on where you are located, and several organizations that propose changes to such regulations. Without getting into too much detail, regulations such as the Federal Motor Vehicle Safety Standards and bodies like the Society of Automotive Engineers are key players in the change in both regulations and standards for headlamps.
Any LED bulb, retrofit, or just an OEM swap, will not be DOT-approved in a headlight application. Typically fog lights, front/rear signals, and brake lights are the only exterior lights that are able to be LED retrofitted without worrying about their legality.

you might be thinking about early versions of LED headlights, they had diodes going all the way around. Or maybe HID bulbs? Those don’t have the correct reflector shields on the bulb. Both of these bulbs give off a lot of scattered light due to the 360° light pattern coming off of the bulb in the reflector housing.
newer led bulbs like the ones mentioned in this thread, when properly oriented as described in this thread, produce a beam pattern that is is almost exactly like the halogen beam it’s replacing. Amazons return policy allows you to buy and try with no risk so you can see for yourself.

You offered me a sets of LED's for my headlights (H13/9008) and fog lights (9140/9145) but when I replied with my address, your mailbox wasn't accepting messages. Any chance we can make that happen? Would love to test and review your LED's!
