FOG TEST - The best color temperature for your headlights? Cold White or Yellow? LED vs Halogens
HTML-код
- Опубликовано: 15 дек 2020
- Hi guys! Today we'll perform some experiments to find out which is the best color temperature for bad weather. We'll take a look at a unique LED design which can change color from cold white to yellow and another 3 halogen bulbs from Osram, Pegasus and.. another one. Beside all this the products will be subjected to an endurance test to find out which lasts longer.

About the rating:
At the end of the video, I thought that it would be a nice idea to have a rating for the products that I test. So, based on the general 5 star rating used all over, I made my rating to better suit my personality. The rating is based on my testing and my opinion of a specific product. It takes into consideration many factors like performance, reliability, availability and many other aspects which are essential to a consumer. Of course, some of these factors may not be applicable to other regions or demographics. As price is another factor in this rating, a product may be cheaper in other regions, rendering my rating as inadequate. In this case, you should reconsider if the product is suitable for you or not.

8:35 With the car on fire it will be more visible to other drivers than ever! Good thinking Pegasus!
In ancient time, the dragon already used this concept.
I wonder if Pegasus will pay for damages with burnt wires and sockets, that should not be allowed to be sold as 55w bulb. At least sell it as what it is so people know. Not a good to max out any electronic circuits if you want it to last some years.
to me the biggest advantage of yellow fogs is when combined with white light from another fixture, the dual shadow of the two colors it casts on road obstacles and ruts, ect. lets you see details WAY better.
In the 80's, I was stationed in Northern California and did a lot of skiing in the Sierra mountains. I had installed a set of Bosch fog lights that were more a gold color, but what I really liked was how detailed I could see the conditions of the road surface. I could even see the white fog line on the road throught a few inches of snow. When I got a new car that had oem fog lights, the detailed was far less and I also experience more strain on my eyes. Now, I have yellow LED fog lights, but I think those old Bosch fog lights were far superior in allowing to see in bad weather.
I've seen those before, but never put too much thought into them. I had some NAPA "Gold" (not really gold colored) big glass ones in a 88 Supra i had, noticed one was dim and tested with how much power was going though with an induction amp multi-meter. One was about 50 watts and the other was down to 32watts, rewired with heavier gauge wire and ended up at around 75 watts each headlight.. that's when i learned that they build in resistance into the circuits to get to 55 watts ;-P They lasted me about 6 years till i sold the car, same with the NAPA wipers they i conditioned and cleaned once a year with PB Blaster (old formula, new stuff is garbage).
Those old lights were designed for racing - as full strength replacements for your main bulbs. If you look at Sebring and other 24 hour races, you will see that many of the cars are running these type of yellow driving lights - much more yellow and brighter than modern "fog lights". And, yes, this was the original design of fog lights - as a second set of halogens at full strength that you could just turn on/switch to instead of the mains. (A/B, not both at once). When you ru both at once, you have to put the yellow pattern underneath the white one as it will be absorbed by the white light. Also, you need to run that setup in high beam mode as most of the low-beam area will be saturated by the yellow light's area. (ie - the high beams need to shine *above* the fogs, not into them), I miss my old Volvo - it also had those Bosch lights in the main grille and an A/B switch on the dash.
Same but mine had yellow lens that could clip on and take off. I tested them and the yellow was clearly better.
Actually it should be Amber. However, have any of you used Thermal Cameras on your vehicles?
Back, when I was studying electrical engineering, they were teaching us the benefits of the yellow and warmer white light at the road. The main benefit of the yellowish light is that it improves the ability to detect and decriminate the objects and also it is easier to the human eye. For me, it is much easier to detect your contour while you are measuring the yellow light in fog conditions rather than the cold white.
Today, the main trend followed by the manufacturers is brighter and more cold white light, that may be looks "cool" but is not the best to use at the roads.
Yellow lamps, I directly start to think about French cars from the 70'ths and 80'ths..
Indeed, '90s were the times when people lived simply and practically, no need for fancy useless stuff in their house, car or...life.
P. S. Range from 3000 to 4200K is usually the best colour for night time.
The reason for the yellow light is due to it's longer wavelength, which allows to penetrate fog better.
It didn't help the driver see, it helps drivers see other drivers.
Since 1992, white light can used on french car. I use osram H7 fogbreaker on a focus ST170, osram H4 fogbreaker on my peugeot 309.
What's "ths" ?
Yellow headlights are still allowed in France
I use the yellow "sun glasses" at night. Really helps with the glare from opposing LED lights by removing the blue spectrum. Also helps with fog and rain. Much cheaper than auxiliary lighting.
Wait, if this is the issue when one could just tint their windows yellow. But, interesting idea ‘coz I’ve been having trouble seeing in the dark now. Sometimes these new cars headlights can be blinding.
I've always had the best results with a very white headlight in combo with yellow foglights to get the best vision in all weather, this is a great channel, really appreciate all the in depth testing you do.
Great video, very informative. I live in a snowy state and run Hella Xtreme Yellow bulbs in the fog lights on my Jeep, visibility is much better in snowy conditions with them vs the white halogens I previously ran.
How is this channel now at 3 million. Your videos are extremely informative and i get a sense of true objectivity and strict scientific testing. You've earned my sub!
Ești genial, întotdeauna o placere sa vizionezi videoclipurile tale.
Great to see continuous improvement on your channel. Also like how your methods are very well thought of. Hope to see more content from you in. The future. 👌
Keep up the good work!! Perhaps the most excellent tests out there!
I have learnt a lot from your channel Sergiu, and your tests are genuine. You have earned my sub.
we share same thoughts about this channel, plus notification 🔔
Wow, that's a very informative comparison.
This video is amazing. I can't even process the amount information given by this guy! Hats off sir!
Hah, very interesting and well-done video! I’d always assumed that yellow fog lights were about light scattering, but never stopped to think that fog droplets are way too large for Rayleigh scattering. Nicely done!
Superb videos Sergiu, superb channel! Accurate, scientific, facts-based and very thorough in the tests.
Thank you for creating and sharing this content. :)
So basically the white light is brighter but the yellow light is not as bright but way better for bad weather conditions.
i'd say "slightly better", not "way better". I think it is also better for fogless conditions for other drivers, because due to less scattering in the eye, yellow light should have less of a blinding effect.
White light is not brighter. 4300k to 5000k is the optimal daylight light for night driving without causing eye strain. 3000k to 4300k light is optimal for penetrating within foggy and rainy environments.
- Anything above 5000k is just about your liking with how much blue light you want, but it takes adjusting to and is not pleasant for long night drives, but may keep you more alert.
@@TheNuclearBolton well from my experience white light is definitely brighter especially if the wattage is high
@@purplehills56 Yeah, anything without the blue light is good. I don’t know why people opt for 6000k+ lights, but the blue light is nauseating to most drivers and it doesn’t reflect as well as light in the 4300k - 5000k range. Honestly yellow light would be preferred as it’s easier to focus on than blue light, but it’s whatever.
@@TheNuclearBolton the reason they like it is cause the color just looks cool thats why 6k and 8k is more popular I used to have it as well.
I found an aftermarket head lamp for my car that upgraded it to projector and went with a 35W HID 5000K color. Got the distance without binding oncoming traffic and the color isn’t a giveaway that it isn’t stock. My biggest shock was how much better projectors are in fog! They shoot under with much less scatter up in front of you. You really see the difference if someone is in a parallel lane and their standard lamps make it harder for you to see in fog lol!
Yeah retrofit with a good projector is the way to go. Get that sharp cutoff and it shoots so far.
I have installed same in my car, but that is LED. When in snow or rain it is getting reflected a lot.. cant see far due its high reflection. Is it the case for you to?
@hemabairavanvenkatraju5251, you have to understand how LEDs produce colors. LEDs combine red, green, and blue (RGB) light, and these colors refract differently in the presence of moisture. That is why LEDs perform well in ideal weather conditions but poorly in less-than-ideal weather.
On a 2nd gen GS300 headlight design was waaaay ahead of its time. The bulb setup is great for all conditions! The low beams on the outsude, high beams are in the middle, yet they are also the day time running lights in yellow, and stay on when the low beams are turned on. The fog lights are white bulb ( clear lense outside of Japan ) so it actually acts like low beams just at the bottom of the car and they are angled outward. So when the fog lights are turned on ( only functions with low beams ) the day time running yellow lights are actually designed as a beam between upper and low beams which all come to a focus of ONE BEAM for all conditions! GENIUS!!!
I switched to yellow headlights from Hella and I love it. Road signs are easier to see, it's easier to see on dark back roads, it's easier to see in snow, and I feel like it's over all better on my eyes
Thank you for the time and thought you put into this.
Very interesting and appreciative.
All explaination and the test were spot on..
Also additional explaination is.. with yellow light coverage, it increase contrast of the projected surface, so easier to human eyes to determine obstacle/hazard on the road surface as well as keeping safe driving in correct lane/road surface...
Especially on the snow...
The same explaination of using yellow tint sunglass lens while driving in snow/night fog
man... amazing experiment! with consistent results, thank you for sharing this information
Thank you for the comparison, you put a lot of effort into this, and it's appreciated! We get lots of fog, rain and snow here so I'm going with some Alla Lighting 5200lm AL-R, 3000K Amber Yellow, hope they last.
All your tests are accurate and great.
Keep up the great work. I love your channel.
Excellent video Sergui and very informative for people who don't understand the workings of car headlights. I've been saying this for years on my forum, but people just didn't understand my point ( or didn't want to! ), some people still see it as the brighter/whiter bulbs they buy, the more they will see at night!
France many years ago used yellow headlights for the exact reason you mention, you still see yellow fog lights over here ( I live in France ), there's also a very good reason why street lighting uses Sodium lights, as they emit a slightly yellowish tint to see better in bad weather conditions.
Also, there's an excellent reason why 'shooting glasses' have yellow lenses ....................... you can see much better through yellow tints ; )
Hopefully now people will wise-up about HID and LED headlights, I've always hated that harsh bright white light coming toward me at night, not only does it hurt my eyes slightly ( causing me to look away ), but I can still see the lights in my eyes once the other car has passed!

Awesome video as always, cheers from Italy!
Thank you kindly. Interesting, informative, I appreciate your effort and look forward to seeing your next test.
Ti-am spus ca esti foarte tare! Keep up the good work! BIG THUMBS UP FOR YOU AND YOUR CHANNEL!
Good video, Sergiu. Thanks for your experiment sharing 👍🏻

I really like your endurance testing rigs. Homemade! 👌🏻
Fantastic video, very comprehensive… thanks Please keep it up!!!
Brother your knowledge is exhaustive and comic timing is fantabulous.
Love your content ! Felicitari ! =)
Amazing video. Greetings from Argentina!
Very good tests, best i seen.
Very useful Video. Given information about all important aspects with details and honest review. Thank you.
Interesting 😀 Nice new graphics as well 👍
Very good work...lot of research work is done
Not gonna lie didn't think I'd get much from this video. I'm so glad you proved me wrong. Learned allot
Very good job Sergiu! 👏🏻👏🏻👏🏻👍🏻🤗😷tnx!
Great video! Very informative.
Very detailed information 👍
This is one smart dude, great content 👍
Good job my friend, realy like your videos
Nice work bro. Well done
Placing the lamps close to the ground is also a good idea;)
Very informative video, thank you...
Felicitari. Foarte placuta documentarea!
Great content, clear english!! Thank you.
Hello, that's a good test!
I used Osram fog breaker bulbs for foggy confition, but they were too yellow to have a good output.
The best products i found was the Narva Contrast + (100W), good in all condition, and really perfect in foggy ones.
Now, with "new generation cars", i use Xenon 3000K in fog projectors and 4500K in low beam.
(I'm leaving close yto a river, and i have a lot of fog)
Short wavelength/high color temperature lighting is on of the worst things to happen to driving. The unmitigated brightness and glare blinds other drivers and eliminates any semblance of night vision, which is critical to safely driving in the dark.
In a perfect world, the market will be dominated by high quality 4000k to 5000k LED bulbs, followed by those that emulate OEM halogen warm white LED bulbs.
@@4G12 The world IS dominated by white LED headlights bro. We are no longer in 2016. Even cheap economy cars are starting to come with LED lights as standard. and 4000K to 6000k is the standard.
The rest of the cars on the road are Halogen, with HID being essentially extinct these days.
The right brightness is key. People get stuck on color temp. Some people just don't care about anybody else and buy the brightest ones without any thought. Also, people aim their lights way too high. The worst are overpowered reflectors. The glare alone is blinding.
Warmer the light the better one actually sees.
Cooler the light the more perceived brightness.
Perceived brightness doesn't equal to seeing better.
Its a similar scenerio to beam pattern vs lumens
Ill take a wider beam thats perceived as dimmer over a narrow beam thats perceived as brighter
@@PghMtbRides uhhh the human eye sees blue and green better in the night, than it does yellow, we see yellows better during the day.
Great video, thank you!
Interesting channel! You are like project farm, but a little more tech oriented. I dig it.
Daniel Stern has a good site explaining the yellow/amber lamp.
Similar to how the atmosphere scatters the blue light from incoming sunlight, which leaves the amber tone in direct light. These bulbs should operate in a similar way. With yellow amber light penetrating fog much easier than blue light.
That is a really interesting video, thanks for taking the trouble.
Don't really care about lights, but the dedication and professional of your video shows. Hope your viewers appreciate the effort it takes to produce such a detailed and quality product.
Brother.. hats off to your efforts.
Bravo bravo bravo,spor in tot ce faci.
You speak excellent English. Thank you for making this excellent video for our instruction. You are a good person.
great test
wonderful testing... ur great EFFORT IS INTERESTING... I feel ur effort when i saw ur vlog... that is why i watch until u finish, its hard to do that.... thanks to u... recommended for all, this is for future refference...
Great informational video! I believe that yellow lighting is better in adverse weather due to the contrast that it creates on the surface of obstacles not really on the amount of light it can reach.
This is why old street lamps (in the UK at least) used to have a yellow sodium hue. They didn’t match the light output of white lights and made colour identification more difficult but they increased contrast which made it easier to see other road users. Now most street lights are white LED which increases brightness and colour definition but reduces contrast. LED street lights also reflect more off wet surfaces, meaning they create a lot more light pollution, making stargazing more difficult.
Bine facut si informativ ! Mia placut si am invatat ceva nou despre un subiect de care eram interesat, numai bine !
Felicitări dragul mami ! Sunt mândră de tine !Te iubesc mult !
Sergiu, You are bloody awesome! I love your accent, my European friend!
I'm using that changing color LED. Thanks for the test. :)
I find I can see better with a slightly yellow light over the blue/white lights at anytime
Our eyes are used to see in yellow light... Tht might be a reason as well
Felicitari pentru postari de calitate! M-am abonat la canal.
Lots of effort in your test.. got a sub here.
nagyon jó munka Gábor! Biztosan mérnök vagy, de így is remek türelmed van. Bár csak tudnám a kocsjaim szerelgetni ilyen barátokkal akik ekkora tudással bírnak
100% the best bulb reviewer on RUclips
Great test Sergiu! I would love to see this test again using other name brand bulbs, since bulbs from the chinese market can be quite unreliable and sometimes….flammable…
very good video. Interesting results
My only thoughts on the Pegasus bulb's odd shape could be one of 2 things.
1: The glass needed to be kept farther away from the filament due to the higher wattage to avoid cracking
2: Could be operating similar to HIR bulbs where it reflects the IR component of the light back onto the filament
But... the huge power load... you might as well get actual HID replacements. Not a "refit kit" but an actual set of projectors. Otherwise your replacements will just end up blinding others as Halogen lenses with HID bulbs is always a disaster.
Warm light is always better. Cold light in foggy weather makes "blue wall" which shortens the light distance.
Nice hardworking, thanks brother from India
I'm scratching my head. Watching the quality of this video, not only in visuals but explanation factor merits a presenter has easily reached the 1 million sub mark. I look down and he ONLY has 28k+ subs!?!?!?!? What is wrong with this picture???? Clearly Sergiu, you deserve millions of Subs!!!
Thank you for this test :) The Pegasus bulb shape remind me of an HIR bulb , it's coated on the inside with an IR reflective coating to make the filament glow hotter and be brighter for the wattage consumed ... It would be interesting to see more information on those Pegasus HOD bulbs, especially the all white HOD Magus Zenon Clear , the website is lacking and so is a buying source for them (interested in installing them in the high beams only because of the wattage)
Thank you for recognizing the effect of the auto camera settings and using manual control.
I worked with some truck drivers in Alaska back in the 90's, they tried about every color light available for driving in snow storms, they all said that Blue light actually penetrates inclement weather the best, but forward shinning blue lights are illegal except for emergency vehicles, but they still used them in remote areas.
I would really like to see if the motorcycle halogen products from Phillips, Osram and the other competitors are actually more reliable than the "regular" versions
Yes they are
Great video. The best I have seen (24 videos before yours)
Great video 👍
I noticed with the "vibration test" that they were on a board being bonked up and down. Typically within a headlight unit, they wouldn't be getting bonked like that. I would like too see a better setup for a vibration test that represents more real world style of driving because the vehicle would absorb most of the hard hits from like pot holes or hard bumps. Just something I wanted to point out. Overall great video though! I do live in the Midwest where we do get a lot of fog.
You really got creative with that drill mechanism for the endurance tests lol
If you ever do something like this again, I'd suggest a 555 timer and a MOSFET, both of which are a dime a dozen.
Good video man👍👍
Yellow led light(especially in fog) is so much better and is so much more visible than white light. The new LED white lights tend to be blinding and are safety hazards for oncoming drivers. Yellow LEDs are less intense to the eyes, which are preferred. So I'm not sure why some people prefer aesthetics over safety. I mean I guess they prefer to be beautiful and die. But what's the point of trying to be beautiful if they can't show the beauty to anyone when life's cut short? 😂
It will be interesting to compare them on wet road as well. My Renault Capture with LED headlights is terrible during nights when the road is wet. It is almost like you don't have headlights on.
Yeah
.same as my car. During good weather at night, my headlight is shining like a champion. When it raining or after rain, my headlights shine like a dick.
Really impressed by your testing. I believe it has more to do with how the light is aimed or projected out not to reflect back at you than anything. Try driving with high beams in the fog vs driving with only the low beams. Quite a difference.
that has an effect but color plays just as much roll... ruclips.net/video/XQheqka2veE/видео.html
@@gatorage850 I watched the video and saw the difference. One thing I hate with the high power led lights is the backwash from highway sign. Sometimes just blinding.
Good vid! Thanks
Good information
On my Jeep JK that I owned, i switched to LED headlamps and noticed straight away that they were far brighter than the factory Hella halogen's it replaced...
HOWEVER, even in perfect conditions everything blended in especially wildlife and I wouldn't see a kangaroo until I was right on top of him where as the Halogens it was far easier to spot things further away.
Went back to the OEM Halogens within a few weeks.
Very good videos - I'm a fan!
Can you also test different taillights and signal lights as well? :)
