For so long i thought it was just there to change angles of the mirror! MIND BLOWN!!!
Thanks for watching!
BrainStuff - HowStuffWorks They won't answer. Look up refraction. Light properties are fucking amazing!
狐健 kitsune ken Why I'm not surprised that you didnt know... Hmm something tells me about Asians and cars...
Hollyweed hehe i think USA has more Road Fatalities per 100k vehicles than China and Japan. en.wikipedia.org/wiki/List_of_countries_by_traffic-related_death_rate
Kitsune Ken I thought that too
"Get into a parked car, preferably yours." I like the humor you add to your videos.

That moment when you realize that the "old time tab mirror" is newer technology than what you have in your own car.
What car DO you drive, Cody? You got a T-bucket hot rod you've been hiding from us?
Well the body is an 87 ranger but a lot of the parts are off an 83 and I recently changed out the engine with a 4 liter. and for the record, I do actually have a T-bucket that can be seen in the background of a few videos.
That moment when you've just finished watching some Cody's Lab videos, then jumped to some random part of youtube and there's Cody in the comments.
(I really like your videos by the way :))
I've been driving the same car for 29 years, and it was already 20 years old when I bought it for $300....that moment passed a long time ago. Sometimes newer isn't necessarily better. My old rolla is nearing 50 years as a daily driver, me being the third owner. Easy to work on. Not much to break. 50mpg. It came with a radio, heater, windshield washers and a cigarette lighter.
hi I love your vids keep it up
I'm driving for almost 10 years now, and I DIDN'T EVEN KNOW THIS FEATURE EXISTS!!! I feel so dumb right now. It's just, somehow, nobody told me about this. :O
google "how do rear view auto dimming mirrors work"
hope that helps
Also, you might not know this, but if someone else is driving, and if you put your ear down firmly on their left knee, you will be able to hear them say "WTF are you doing, you freak?"
Try it for yourself!
i didnt either but while messing with it i knew it just flipped up and i always used it when an asshole has its brights one which is just about 80% of the time at night.
can there be a rear high beam for those assholes 🤔
DoubleM55 You must be female.
Drove an 85 Ford F-250 for a year with the steering wheel almost all the way down. Then my dad showed me on his truck to push the blinker forward to adjust the tilt!!!
Then I tried pushing my blinker forward on mine...sure enough I had tilt steering.

Aaaaaaaaaaand Subscribe!
break check, heres what works. get off the gas and gradually slow down. he will go around. then you can test your bright lights as he drives off into the darkness.
So instead of one idiot on the road and one driver who uses the dim option on the mirror, you get two idiots on the road. Genius!
not if others follow my lead. then there will be an army of idiots on the road.
heres something to think about. when Google car is the law. will you complain that you want to drive yourself and be the dangerous person behind the wheel, instead of the safety of google car
d'nomar senoj I have no idea how the google car is relevant to your idiotic road rage behaviour.
More commonly known as "Brake check"
I realized that if I flipped mine into "night" mode during the day, I could see my daughter in the back seat AND the road behind me at the same time.
He should just, host this show all the time.
Josh! You and Chuck are awesome!! I love your podcast! Keep up the good work
This is the most useful and well put together video I have ever watched. Bravo 👏
this guys like a polite Christian Bale
yoooo!
thats iiit, I was trying to see who he looks like
Please, WHERE IS HE!... Thank you
I have a rear view mirror! Unfortunately, no car attached to it...
Once I seen Josh on the video explaining, I automatically had liked it. I love the stuff you should know podcast.
Thank you so much for this video , I just tried this today and it worked !! It has been so frustrating being blinded by those hazardous blue lights glaring behind my car !!!
Very interesting and nice video. I learned something new. Thank You!
Thank you for explanation
In your animation of the mirror, in daylight mode both the bright and the dim reflections are going in almost the same direction (the bright one hitting the eyes and the dim one hitting the chest) but when the magic tab is toggled the two images are at 45 degrees or so.
Some rear view mirrors can actually continue to dim the lights progressively, the more you move them. Throw the tab, and if you still need dimmer, try moving it by hand. The first time I found this out, i was like "my whole life has been a lie" how did I not know this.
The moment I heard your voice, i was like, "STUFF YOU SHOULD KNOW!" Love the podcast :)
That's really cool actually. I want to know; how do your organs stay put when moving around a lot?
Good question Kaleb! We'll add it to our big list of future topics!
Thanks brain stuff!
Ligaments
They're packed in there like Sardines, that's how.
They don't mine move about with me where ever I go.
If yours don't you need to see a doctor or if it has been happening a for a while an undertaker.
Great video! My mirror is looking terrible and I thought that I needed some really exotic glass to fix it. Thanks!!
I always wondered how those things worked!
nicely explained
we don't take it for granted. we just aren't aware they exist or how it is they truly work. Thank you for enlightening us.
Youre so funny dude which is why i Liked subscibed and got the T shirt a long time ago. Thanx man.
Thank you 🙏🏽
I listened to this bloke on podcast for years - this is the first time I ever saw him, what a good looking chap!
Holy smokes you have opened my mind! I've been seeing double reflections in my mirror for a while wondering why? And now I know, and don't have to bothered by obnoxious brights from behind!
Before this video I honestly had no clue rear view mirrors have tabs. Going to check this out.
That was lovely.
Great explanation. Maybe even better if the surface of the mirror from 1:05 had been shown angled down rather than vertical, which would be consistent with the incident rays coming off it at an angle from 1:18.
thnks sir you r the first who make video o this topic
“A parked care preferably yours” took me out 🤣🤣🤣
Thank you
I just installed this mirror on my Mazda. Should the anti-glare switch be on the bottom or top of the mirror? Thanks.
"Get into a parked car, preferably yours" lol
This video got really weird, then normal, then really weird again. I'd bet Josh is the Kafka fan in the brainstuff video crew. They aren't all out to get you Josh, unless they are.
Thanks man
1st part EVERYONE knows, 2nd part NOBODY knows. I feel the power of knowledge surging through me
What is the function of fuzzy dice hanging from the mirror on your thumbnail?
to be fuzzy
They serve the same purpose as the flames painted on your doors, the naked lady mud flaps, and the 8 ball shifter - show 'em how you roll!
photondance And I always thought that they showed the driver's IQ by combining the two of them; Highest would be 66. They also block the driver's vision and create one more thing that may lead to an accident.
I knew it angled the mirror but I didn't know the rest cool to learn new things! :-) :-)
thanks for watching!
Look up the "double split". Physicists don't understand many things.
zENDERz *Double SLIT
We have been using this tab all the time to switch between me and my mom as drivers because we share the car and i am taller than her...
same
I've never heard of this being used but I'm gonna go try it on my car.
parmmodh
The only things I miss about my old Dodge Ram are the fog lamps and the electronic mirror dimmer. It adjusted automatically depending on how much glare I was getting, so I could still see clearly if I only had a little glare.
Hi, can you explain why there are two dimmer glass reflections (one above, and one below the brighter mirror reflection) when i look into the rear view mirror? According to the video, there is supposed to be only one dimmer reflection, but i'm seeing two, could you explain why?
1:38
Quite clever
Why does Josh Clark not have his own channel yet?
Genius engineering!
for accuracy, the little arrows showing light hitting the mirror and bouncing to the eye should be at equal angles
I did not know this existed O.O Will be trying it...
Yeah my 2015 wrx has an auto dimming mirror so i don't gotta worry about some tab lol
I love this guy
i got my toe stuck in the faucet
same here man, same here
AlphaOmega Buy her some clippers.
Haukenslush Happens to the best of us.
sad not too many people knew about this,. very helpful during night timefreway
I was able to answer the question in the title before watching the video.
It is a great invention.
I'd so try this, if I had a car
i'mwith you, but i'm missing the flashlight
Use your smartphone if you have the flashlight widget
GhostHostMemories
all phones these days have flashlights
This is interesting,,,, Why do florescent lights buzz?
Huh... good question Ryan. We'll add it to our list of topics to research!
Love this show!
It's the sound of a rapidly switching electrical arc between the anode and cathode. It's the same buzz, essentially, as you get off a Van DeGraff generator.
OMG, I was suffering for so long!
cool. Good to know
You would have to be living under a rock to not know what that tab does.
i think people know that it "dims" the reflection, most people don't know the physics behind it.
Boodieman72 I had no clue but again I don't own a car and I hardly ever drive
i'd respect that tab more if it turned on a 1w green laser aimed at each of the offender's eye.
Great 1 I wondered whats its used for . I don't have a car but love to know what car functions are like . lol
OOOOOOooooooo. Prismatic wedge. Sounds fancy.
Does is still flip left and right but not up and down?
I've been driving for 5 years and only found out a few months ago what that tab did... No one taught me =/
I figured it was something like that. I remember when I didn't know I had that on my mirror, I would just readjust it just to get the light out of my eyes. Now can you do something about cars passing you with hi-beams?
I didn't know this had to be explained lol I knew what it was before I had my license
darkeyce02 but did you ever know how it worked?
0:38 If you have to do that, then you have your side mirrors positioned incorrectly. If you have to look over your shoulder to make sure a car isn't in your blind spot before switching lanes, then your side mirrors are positioned incorrectly. If you can see the side of your car in your side mirrors, then your side mirrors are positioned incorrectly.
Ideally what should happen. You first see the car in the center rear view mirror. As the car comes up along side you it reaches a point where the front can be seen in your side mirror, and back in your center mirror. The car moves up next to you more, and you then should be able to see the front of the car next to you with your eyes, and the back of the car in your side mirror. The only way you should be able to see the side of your own car, is if you have a domed side mirror.
This is very possible to do. I have done it successfully with every car I have owned. The only time I ever have to look over my shoulder to check traffic, is when I'm driving someone else's car.
Draggon Reaper when your driving someone else's car? ... Can't you just reposition the mirrors???? Seems very stupid to me after you wrote that whole lecture on mirror positions...
I don't mess with how other people have their car set up. I don't like it when people change things around in my car, so I don't do it in theirs.
Draggon Reaper lol.. Even when you can't see properly? You reeeeeaaally shouldn't be lecturing other people!
I. LOVE. THIS. GUY.
So that's why I can see my mums eyes on her forehead faintly when I'm in the back sometimes
His way of explaining things reminds me of Phil from The Last Man on Earth ☻
I like the video. . . For Claroboy011: As far as car crash accidents work, that is a good question. I learned in traffic school that if you look towards the reflective line on the side of the road it can prevent accidents.
I'm surprised how many drivers I've have to tell about this in the past.
"Get in to a parked car, preferably yours..." Loved it. Just learned how to use this mirror tonight and wanted to see how this voodoo magic worked.
When/why was HowStuffWorks split from Discovery?
Discovery sold us to another corporation in April of 2014.
I've been telling people these things for YEARS! maybe they'll listen to josh....
I didn’t know this was a thing!!!
Different country's regulate the mirrors differently. In canada all of our angle down. And not up. My friend imported a Japanese car once and it was angled up. The premise is the same either way though
OMG< i though it used to tight and loose mirror angle to adjust !
I got in a parked car, at night, with a flashlight, now I have to report to my probation officer.
Can u do a video on how the persons body organs react when in a car crash? And around how many crashes can organs take ? Please and thank you
I'll add this question to our list, but I suspect the answer varies widely depending on the kind of crash and the person's position in the car. Whether they're wearing a seat belt probably changes the effects as well.
BrainStuff - HowStuffWorks still would be a good idea to do a video. It would cause conciouznes to Pple watching. And show this channel cares about there subscribers
+Alarm Tech911 right, because if they chose not to do such a video it would prove that they don't care, and we wouldn't want that now would we?
+Mike Koehler wtf, I read this comment today and it seems so bitchy. I probably didn't mean to sound demanding but it seems like it XD
lol, no problem. I didn't mean to make it sound so bitchy either. In fact I kind of just laughed at it. No worries.
the only reason i clicked on this video is because i was confused on what tab you are talking about, still after watching the video, ive never seen or heard of those tabs
Yeah
Joshua Allan-Sloper I drive a 30 year old car, I doubt it has it
Bro, I've never noticed it before, its more hidden on the back side though.
Wow. I just purchased a small car as a substitute to my Jeep which has electro chromatic rear view mirror. And my Nissan doesn't. Now I can easily dodge those idiots behind me without spraining my back.
backwards? do we flip the tab forward or backward?
also u can prove this by simply angling your head lower and looking up into the dimmed rear view mirror ..u will see the dim image and above it will have the "normal" reflection
Also good to adjust it in the afternoon because you are actualy shorter after being up all due to gravity pulling on you spinal cord
So why does the mirror either point up or down. In other words...I can flip the tab up and adjust it to see the headlights brightly...then flip the tap down and it “dims”.
Or I can flip the tab down and adjust it to see the headlights brightly, then flip the tab up and it “dims”. O
One way I see the slight reflection of my seat, and the other way I see a slight reflection of the ceiling. Is there two pieces of glass? Or just refracting.?
i like the way u said "prismatuc wedge" HAHAHAHA
"I drive really slow in the ultra fast lane, while people behind me are going insane!"
"get into a parked car. preferably yours" thats a killer
The automatic dimming mirrors transmit much more light than the old tried and true flip rear view mirror. I wish my new car with its fancy auto dimming mirror could protect my eyes nearly as well as the old school flip mechanism rear view mirror.
I never knew how much I needed it until I bought a car that didn't come with one. I also moved to NY where for some reason a lot of people think it's okay to drive with their high beams on when they're driving on the highway.
lol love the sarcasm haha
For your side mirror just add tint on them
Hmm. Well there goes my theory about it being done with pixie dust and unicorn jizz.
This dimmer tab and the little arrow that shows you which side your Fuel door is on are two things I find people know NOTHING about....
I thought everybody knew about the mirror tab. Nobody had to tell me.
+Bungman Agforty that arrow thing is only for the us market i believe. I've driven almost every brand of cars in EU and not one of them had it. Talking about cars aged from 1960-2015
Spitfire83 Perhaps not EU but it's done in Canada.
Dont forget the turn signal switch
Frank: Yep. So many apparently don't know how to use them. Pet peeve of mine. Not only is using one the law, but is also simple courtesy.
Great videos but maybe it would be better if they were 30 seconds long so we could watch more interesting videos like this one!
Wow, I'm really stupid, I thought it was the other way around! I thought the dim setting was for the morning when the ambient light out is too much. And the bright setting was for night when you can't see as well, lol. Well I'm photosensitive to daylight so probably....
How can we dim the side mirrors ?
The driver's side, side mirror, always gets me at night, LOL.
