I'm not gonna do this to my car, but i'm gonna watch it anyways
lmao same
+Christian Kinsler yet we still watch
+Christian Kinsler Basically sums it up XD
+Christian Kinsler its a good idea to do anyway it takes the load off the headlight switch I did this to my old truck headlights are much brighter now
Yea my car, BMW 330ci has auto lights! Never have to worry about leaving them on!
I just suffered from a forgotten headlight induced flat battery today, got home and this was waiting in my subscription feed. Perfect timing. Thanks MCM!
i played it safe and jacked up the car first.
😂😂😂😂
+Kaahaaja1 make sure to put them on axle stands for extra safety

+Mighty Car Mods BEST VIDEO EVER!!!!!!!!!!!!!!!! you guys are bloody awesome...............much love
+Mighty Car Mods Fuckkk yeaaa
+MixVids why?
+Mighty Car Mods actually starting up an engine while headlights are on is a bad idea, it affects the alternator not the good way
Marty looks pretty in pink
lol 😁
+Galápagos Turtle :D:D:D
If i didn't own an s13 with pop up lights i would totally do this. Great quick original DIY video guys!
Hey man love your videos
+Kalvin Malli (ThatBurgundy240) Hey u are the guy that apeered in rudniks vid!
Same mine's a z31 lol maybe the halo could be ran off this
just got done watching the latest roadkill episode then this vid popped up. awesome
[*-*] great timing RK+MCM FTW
+Wtrxprs007able Nah, RK+MCM+HG
Holy shit, I just did the exact same thing.

+The Pumpking King But he always says that though! LOL
You guys are awesome. So many episodes in and you still find a mod that goes all the way back to your roots! Simple, cheap, and effective! Congrats on best channel award!!
6 years later and I'm going to give this a go on my kids first car. Quick cheap and easy 👌
I love the major mods you do like turbos, don't get me wrong. However I personally love this type of mod. You guys are awesome for doing these little mods, putting "luxury" or "modern" features into any car. Just doing anything like power mirrors, backup camera, remote start, ambient lighting. All the cool mods that just make your car yours!
MCM on my birthday is the perfect present. :)
+David F. Happy birthday!!! =D
+David F. Happy birthday man!
+David F. Same here man! Happy birthday!
+David F. jaja
+David F. mine too!
I don't have a relay like this in my Magna, but a constant beep drones on if I don't turn the lights off when I take the key out of the ignition which is kinda cool and annoying at the same time XD. Love how you actually illustrated a basic diagram for the electrical connections in this episode. Production quality just keeps getting better and better. MAAAAAD!
Wow a video! See you in 2016 lol
+Henry Hazlitt ....
so true lol
so many awesome projects coming up.. can we at least get some highlights on what is happening with the other projects.
mini is cool and everything, but i want completed mira project, and othrr stuff..
they've uploaded 12 video's in the last 2 months...
No i want a project build.. Not these little videos.. Kinda like the kei to the city.. An hour long brain smorgasboard..
Don't get me wrong, i love these little snacks.. But i wanna binge.
Really digging the return to DIY and I love how detailed this video is. Good production too, keep it up boys.
Wow, you got a JDM Marty for this video!
Wow! You guys have seriously upped your production value. Great job! I love how clearly and simply you explain the relay and the shots you picked illustrate how it works and how to wire it in perfectly. I hope this new look is a trend that continues for the future.
Thank you Toyota for thinking of this 30+ years ago with my USDM 1985 Corolla GT-S (AE86).
The head and parking lights automatically turn off when I open the doors while the car is off. Even if I turn off the car after I open the doors, the lights turn off. Then, when I restart the car, the lights turn back on. On a plus note, the lights do not retract when the door is opened, they simply turn off.
I had an 85 celica gt that did the same, always thought it was cool that I could leave my headlights popped up without mods and not coming back to a dead battery
+e30rik Yeah, my wife's '82 Lidtback Celica GT with the "S" option and my brother's '86 MR2 did the same thing, it was awesome.
My lexus is300 has automatic headlights, night and day sensors as well. But it sorta has a defect. If i turn the car off and stay in it, the lights will stay on. I found this out the hard way. I once parked my car and went to sleep in it (in between college classes) and woke up to the noise of my relay clicking. Car was fully dead. I figured they would turn off automatically as they always do after
+Mario Tejada 1min as it always does
+Mario Tejada Toyotas are the same, the lights don't turn off till you open the door.
I just wanted to say a big thank you to MCM. I ordered a keychain from your website and I recieved it very quicky (less than a week) & The quality is awesome!
There's a continuity error at 0:53 - Marty wasn't wearing his hat and suddenly he is.
Now THIS is MCM. No super-choo-choo worth thousands of dollars and made with experts few have this much access to. This is great, thanks guys!
"Mount the relays securely, and reassembled"
*pushes them into a crevice and reassembled without securing them*
now this is the videos I've missed from you guys glad to see you guys are back
For some reason, my friend's amp for his subs pulls power from the battery for about 5 minutes after the keys have been removed. Definitely doing this for his amp.
Really useful, not just fun to watch. Good one! We've had mandatory lights for a long time, but auto headlights has really only been mounted on domestic market cars, whereas people with imports always forget them on, or forget to turn them on.
MCM, please do a video on how to install a aftermarket digital dash system, such as a Holley EFI.
I would love to see that and also to see cheap and easy mod will give us a little bit of power will be amazing
They wont do a how to for holley that's for sure. If they do one they will do one for halltech and really you don't need a how to. They have shown in multiple videos the basic install, you can get all of them with a manual that says everything you need to do. Plus most cars are different.
I remember watching this channel since it was just two blokes working out of their garage, now look at em. Keep on mates, good job
Watch a video while knowing you'll never do this mod to your own car just because MCM for life
i'm so stoked about this. it's gonna be a real mcm season like back in the day. maad.
congrats on the award, guys!
I'd sooner see N/A tuning than another turbo, hopefully that's what they do because the mini is renowned for having that small engine tuned out the wazoo!
That's it, took me just over a week of watching you guys after work and I've caught up with everything. Can I just say that you guys are the best and Kei to the city is the only CD I have in my car now... Keep on doing what you do, you're both awesome :D
turbocharged mini?
+Alberto Pettine That's what I'm thinking. I think the intercooler in the box is a bit of a giveaway, don't you think?
+Alberto Pettine and the fact they are at AM auto is a give away too.
Nah man b18 swap
+Lucas Ocampo im with you dude
+Ben Ward MAybe it's going to be supercharged like modern coopers
glad to see the original MCM mods coming back. Love the crazy cars but taking MCM back to its origins is a breath of fresh air
And the girl??? What happened to her?
Leandro Kuschill what are you talking about m8?
marty was wearing a wig mate
Leandro Kuschill That's Marty man. How can people be so stupid.
@unshockable lol
Fantastic video. Love the cheap DIY's that got you guys going in the first place. I like the bigger builds too, I'm just glad you guys haven't forgotten the cheap easy stuff.
Wtf is that Tshirt Moog is wearing?
+PlainSailingWeather I don't like the way it stares at me >.>
Curtis Tompkins
I don't get who the dude is though.
+PlainSailingWeather its an instagram post of one of moogs mates.
+PlainSailingWeather i thought at first it was aaron kaufman its very distracting!
+PlainSailingWeather It's an add for some guy on instagram
Going back to your roots with some cheap and easy weekend mods, very good to see. I can't wait to see what else this season has to offer.
Mcm and chill
this is a next level video, in terms of quality of the filming, camera, etc. Looks great! Well done!
Soo who's the chick with the pink hair?
Marty
marty m8
+Christian Augustin I reckon they are transitioning to new hosts. Just breaking to us slowly.
+DxsPro Don't say that! That's frightening
Kobi Jenkins K her name's Marty but who is she?
I am in love with you guys adding previews to your videos.. it let's us know your already making the next video. excited...
Marty gender bending like a wizzard
Electric space wizard?

my Truck has auto lights but I'm going to show my friends this!! You guys are friggin awesome! Favorite channel on TH-cam by far. my friends complain because all I do when their over is watch your madd vids
4:10 what track is it??? please
Loving the DIY aspects coming back :)
keep it up boys
I pulled out my jacks and jack stands, didn't even need them
Thanks Mighty Car Mods for helping me do this installation i always leave my Monaro headlights on and had to be jump started. You diagram on your page helps me so much.
THANK YOU MOOG AND MARTY
FROM MCM FAN!!!!
10 dollars? Nah just buy a Subaru mate ;)
Your editing has really improved, every episode your videos seem to be transforming into a professional show, gg
Subaru Life: already have it
I was thinking the same thing *subaru owner fist bump*
since at least 1992!
+Matt Hester Fozzy checking in! #autooffforlyfe
I have a 2000 Forester and it's standard, Subaru's are great
+Matt Hester
I thought all cars did this until I drove my sisters Honda. It was 10 years newer and the lights did not auto turn off! (Had a 99 Legacy GT at the time)
I really don't understand why you two haven't been picked up by some TV broadcasting network yet....You both have great "TV" personality and your videography is awesome!
+garretts91 they have definitely been approached by every broadcaster everywhere (i'd say its a safe bet even the BBC have contacted them after clarkson was axed), they just wont do it because it would ruin the show.
But are you able to turn the lights off while having the key in? And can you blink your lights while driving?
Hörður Heimisson yes, you're just putting the solenoid in between the switch and the lights.
So this only works when the headlight switch is on?
yes
You can easily modify this relay set up to have a delayed auto headlight off feature with a capacitor, and even make it adjustable with a potentiometer. Maybe another mod would be to add on an "Auto" feature where you wire in a Photo sensor so only the headlights come on at night. (Relay that opens with Photo sensor energized). Keep up the good work MCM, I always look forward to your videos!
WHO WAS THE GIRL? WE NEED ANSWERS.
I followed MCM directions and looked and my wiring diagram and figured it out on my own........thanks MCM
this is rubbish, auto headlights means power going to something other than my wheels. Do a headlight delete instead!:)
+Victor Marshall your comment is rubbish.
+daniel leete your face is rubbish:)
+Victor Marshall boy, that escalated quickly
+The Evenger haha
BOY IF YOU DONT GET YO
You know it is a GOOD day when you see MCM has uploaded a new video!!!
Awesome easy mod, cant wait to do it to my ranger. Thank you for including a wiring schematic for the circuit, makes it a lot easier for people who don't understand electronics.
Thanks guys, I really needed it and - what a coincidence - there comes your video. I took me a bit to figure out the right wires as there is one for the rh and one for the lh headlight in my Navara. Quite funny I ended up with one switched with ignition the other one always one at one point lol. All sorted now. too easy!!! Keep the good stuff coming!!!!
awesome to see you guys starting to do a bit more advanced electrical work in your videos, and to see you guys wire it the right way! no twisted wires and electrical tape is a good thing!
MOAR TINY DIY MODS!!! THIS IS WHAT MCM IS ALL ABOUT
Congrats on the award fellas! I recently discovered your channel and I've now watched all your videos on both channels. Did you get some new camera gear? I love watching how your production value has increased over the years. Thanks for doing what you do.
Yeah, definitely need to do this this weekend. I leave the headlights on in my truck on fairly often, because the stupid beeper that told me my door was open and that I wasn't wearing a seat belt was more irritating that occasionally bugging someone for a jump.
Marty and his soldering iron :D I miss the driveway though. Also well done on the award, you guys are the best on youtube.
am I the only one who find myself constantly staring at those wheels? Gosh they look amazing on this car, definitely my favorite part of the build so far.
You guys are the hero's of the internets
Worth mentioning is that this MAY be an accessory circuit, or it could also be an ignition circuit. Accessory circuits will cut power while the starter is cranking (Your radio is typically an accessory circuit, notice how it turns off when you go to start the car?) An ignition circuit will be powered throughout the turn of the key, except obviously when the key is in the off position. I'd probably go to an accessory circuit as having your lights on during crank will lessen the lifespan of the lights! Mad!
MCM getting back to what they do best. great job!
so doing this to my old datto 260z, not only is to old to not have auto off headlights, but it doesnt even have an alarm to say the lights are on, thanks guys this mod might just save me a battery and the trouble of a clutch start
I'm surprised more cars don't do this already. I just bought an '89 Subaru Legacy, and even a car that old has auto-headlights. It's such a useful feature.
awesome and simple mod! I have some old relays and a car that I often forget to turn off the lights in. Definitely doing this!
Hi Guys, great mod.Not to belittle the simplistic parts, maybe a slightly better idea would be to add a little delay in the on and off. This way you don't have any drain on the battery when cranking the motor, and when turned off, there is some light to show you around, getting the car to where ever before turning off. Love your shows. From across the ditch.
Finaly a diy mod! That's why we watch MCM! :)
I would have used 2 different colour spade terminals in the installation, and a tip from me is not to used tape ,the heat eventually makes it unravel and then a potential short situation ! I do Enjoy your vids guys !!!,
Back to your roots........other than the studio you've set up haha, Keep up the great work guys.
An award well earned and totally deserved : ) Is it just me or did Marty looked pretty cute for a moment there ???
You can also wire this through the parking brake switch, so the lights will be off when you apply the parkbrake, but you can have the engine running. Very nice for when you're parked at a "scenic outlook" spot at night, need to stay warm and not annoy other "sightseers". (Also, in Canada, it's important to have a mode where your car is using as little electricity as possible, when you just barely get it cranked over at -40, so your alternator can get the battery chrged quicker.)
Back here again as I just got a '95 Hilux for my son and I to work on. This will be the first mod we do. ❤
Moog, I know that you have sold on the other cars MCM has modded but I think the MINI is so rare and unique that you should try to hang on to this one forever. You don't want it to become the one that got away.
Cheers!
This is brilliant I am heading to get the parts in the morning all o need is 2 horn relays and I don't need some special Universal kit with a million wires for 4 lights
Here's a pro tip from a car audio guy. Mount the relays in a nice spot first, THEN run the wires up to the spots to be soldered and cut them to the right length. This way you can put the relays out of the way and make the wiring cleaner looking.
(this is also the best way to install alarms/central locking/remote starts etc.)
Mount the modules first. Then run your wires to the solder points following the factory wiring.
Congratulations on the award guys, well deserved
back to the roots of MCM! :)
Will need to give this a go with my older car, good thing my 09' Lancer has auto off after about a minute or so, like all new cars should be! It also has auto stereo off after 30 min if you leave the car on Acc.
Great mod and very easy for those cars without it, even new ones that should have it.
Cant wait for the next episode guys, and congrats on the "Golden Globe Awards" awesome :)
More down to earth mcm vid like the old ones. This was awesome. Still like everything u make though dont take it the wrong way
back to the roots Love the vid guys
ONE thing I love about my Italian car. This, what you're showing is standard from factory. Don't even ask about everything else though... And yes it (Lancia Delta) drives brilliantly. On tuesdays.. When it's 25 degrees.. When sunny.. If it feels like it.. Basically when it hasn't got it's period. -_- (I truly hope my car doesn't read youtube comments..)
you can also get relays with a small capacitor that will hold them on for a short period.
this would be handy so you can still get the headlight on warning (if you car has it another good video idea) so you can switch them off manually of just leave them to turn off a short period later giving you a short time of the area being illuminated
it might be worth it to set it to an "on" power wire. so that when you're on ACC (dash lights off), your lights will be off. plus, having the ON (dash lights on) power for your power wire, makes sure that all power/lights will be off during cranking. not that it matters sooo much, but it can relieve strain on the battery to some degree!
good to see you finally uploading
you guys rock, this help Mr so much, and the subarute rock on!,if roadkill ever come to you still fulfill my bucket list.
MCM with animated illustrations is amazing. Keep it up.
Just gonna assume it was the first Marty that did them (?)
I'm in love with new Marty.
This is a pretty good response to all the people complaining they don't do videos like they used to.
I missed you guys' actual MOD videos.
loved this new style of video. top quality guys!
Nice. For anyone that can't fathom doing this, a $2 jaycar buzzer wired up with power from the dash lights (or cigarette lighter, footwell light, whatever), and earth from the door light switch is a simple way to get a similar result.
Can't wait to see what you guys do with the mini!
Luckily my celica has automatic headlights on/off feature stock. But this is an awesome mod none-the-less!
I used to drive an Impreza. My 2 favourite things were the warp mode button and the auto headlights.
I miss both of these greatly. I also miss driving diesel.
If Subaru made a turbo diesel ute with springs, trayback, auto headlights and a warp mode button, I'd trade in my HiLux TODAY.
