I personally like warm white lights better but mega thanx for the tutorial overall, saved me from taking apart the rear view mirror.

Rear view mirror lights cannot be replaced. They are wired to circuit board. Just wanted to share so no else goes through the hell I did taking it apart and putting it back together. Aside from that thanks flexx for this guide. Very useful and I love your view on mods. This video and many more from you are super helpful! Cheers!

Just done my interior and it has totally transformed it, highly recommended and so easy, also did the boot (trunk) bulbs 👍🏻

Just finished doing this, came out so cleannnn way better than those nasty yellows...thanks Flexx! I always click through and purchase what you recommend

LOL! My kind of guy. I would have done the same on the mirror and rear tail lenses as you. Great tips on the W204 series. And a big hello from downunder!

After seeing you drop that mirror i think ill leave mine alone😮

Are there warm-white LEDs available? The blueish ones are far to cold imho… I like it cosy and blue led lights are just not cosy. Thnx for the tutorial!

to swap the lights on the inside mirror you have to remove the covers at the bottom of the mirror and pull out the old lights with pliers

That’s crazy my c250 has rear view mirror leds already it’s a 2014 still need to changes the headlights 😎

I agree with this guy. If it’s hard let’s leave it. 😂😂

So kudos, I think You did A great job with showing how to install all the LEDS, I Basically went on Ebay and got 20x ULTRA white LED bulbs for around $15...... But my rear sedan dome light takes 3, 2 of the 168/194 Bulb and then 1 center , I can get back but I was pretty impatient so I went to Advanced Auto and bought the 1 Buld LED I needed, it fit perfect, super bright, it's the main light that comes on when doors are unlocked,locked, it's a 6418 WHITE LED. Tube bulb with silver arrowheads on each end... Was like $8. Anyways, I replaced Every light, trunks, glovebox, overhead vanity dome, rear dome=3, flip down driver/passenger mirror lights, , SO I was so Pleased , How could everything go this easy and smooth with NO ERRORS.... WELL, THEN CAME THE LAST 2 BULBS. I HAD THE the bulbs, the same ones exact ones I used for the rest of my car, however when I went to replace them I kept getting wierd things happening.. So at first I thought maybe my bulb was bad, but I still had like 10 left, then I thought the door was open too long, maybe it timed out... No , that's not it, so I took out both of my LEDS, AND TRIED THE FACTORY again, well I was so happy to see that they both turned on and I Didn't blow a fuse. So then I installed 2 Phillips LED WHITE Bulbs while the factory were still lit... so YES passenger stayed on!, now on to driver side.... it was still on, so I removed factory and put in the other Phillips LED, WOW ,So now both are lit so closed my drivers door, and low and behold lol, now I have 2 LED under my feet factory area, and they first started blinking on/off every 5 seconds.... so now wtf??? Im stuck.... this is why FLEXX Did not mention or show us him changing the foot pedal lights out I'm 100% certain, and if I'm wrong , let me know how to fix it. So Anyways I'm not getting any error codes, but it's so strange it's, almost like reverse polarity, by this I mean I did this in my garage close to dark, and when I start up my car, now I have those 2 LEDS WHITE ON ALL THE TIME!!!! I thought well this could be a good thing. I own a super clean sharp White 2014 C300 Sport, so I was thinking maybe I order 2 bulbs in a different color, or a pair with app.... if their gonna stay on while driving...???? Any thoughts here what I should do, or has this occurred to you??? PLEASE HELP ANY way u can!!! Thanks, james

You forgot the trunk light brother. Also, I searched all over eBay, and noticed that you can get the same lights for super super cheap if you buy them from China. Just search 194 LED. My only concern is that they may not be the same quality. Can anyone comment on this?

I tried replacing the lights that are under the dash, the ones that light up the floor of the driver and passenger side, but when I do it, I replace one side (passenger), it lights up...then as soon as I move on to the driver side and replace that one, the lights stop working. I'm guessing it has something to do with the voltage. I bought another set that claims to be error free, hopefully that works. BTW, I thought the same way when I was looking at the rear view mirror lights. Looked complicated and felt more like I'm gonna break something if I tried 😂

Hey Flexx, awesome videos, really helpful, appreciate bro, I'm lucky I have the same car as you. Please check if ambient lighting can be done on the w204 C class.

LED’s are ok for number plates, puddle lights, footwells and sidelights but for interior reading lights they’re just too white, too bright and too unreliable. I did this to my C250 and found the white light was just too clinical so changed them back to incandescent.

Thanks for sharing bro 🤙🏻

Many Thanks. Greetings from Germany 😁👍🏼

Look easy enough!

Omg I did exactly what you said and this didn't pop out easily there screws attached so I'm leaving this to the professionals😢

love stinking channels like this...VERY useful!!!😂😂😂

How instal led on license plaq ? Please

On my 2008 C the only one factory installed led I have, are on the rear view mirror..

They look way better bro...

It's different for the rear lights in the sedan. It's a pain in the ass.

Thanks.

Please I need help. I've looked every where for instruction on how to access the little orange light in the mirror that shines straight down to the gear shift I want to change it to blue in my 2013 c250 can you help?

Wait my 2009 C63 has leds in the rear view factory. Maybe check out ebay.

Buddy you are cool. Thanks a lot. 🙂👍

Thank you 👍👏👏👏👏👏👏💪🏽

How in the hell you got those center light lenses off like that without breaking them? I cracked my both lenses by using your technique..

Hey Flexx, do you have info on changing the side mirror bulbs (welcome lights) to LED's? - 2014c350 oh and a link to the led's you purchased pls Great stuff, brother. Thnx

so does the back dome light fade on and off with the LED installed?

Im just gonna change the dome lights😢

Have you changed the bulbs in the door panels or seat head rest?

Hey flex, do you know where the fuse for the front center peice lights is? The main lights that automatically turn on when you open the door , i was trying to install rgb leds and i have short-circuited them and heard a slight pop noise , I dont know if the fuse is there inside de centre piece or is it in one of the fuse boxes !! Thank you

Hey man, the square part that isn’t a button on the light console in the front was pushed into the console and it’s left a hole. I can’t get back the piece but is there a way get it back? Thank you

what is the size of the sulphide bulb on the back ceiling

Does these instructions apply for 2018 GLA250 as well?

Hey Flexx, What about footwell lights? Have you tried to replace those and take care of blinking issues?

I have a 2014 CLA 250 do you know if I have to do the same method with this on my car? Thank you

Before its better!!! than after! Thats my opinion!!!

Hi, Any error messages from the car ecu?

Hi brother, I want to ask you on these internal lights of the car, it is in my car goes out and work alone I do not know why

You are right to not change map light at rear mirror. It isn't worth to do that.

Do they sell blue lights for a Mercedes c class c250 2012 model?

It’s harder to install the backseat lights on the C250 sedan and the middle bulb is long and the led bulb is shorter so it doesn’t fit

which ones are CANBUS?

Better rgb or something like a blue or red but this pure white looks like otilet light not that nice for a merc,i like incandescent better than this white.but rgb make that shit red or blue will look sick

what about puddle lights?

Hello, there is a wired noise comes from the thing between the dome lights, what is this? Can someone help ?

Is every bulb of interior light it W5W? 🤔

Thanks👌🏻

Any code after replaced the lights?

I have a bulb out on my rear view mirror and hoped you could show how to replace, Don't think i'll bother now. Don't understand why the Mercedes designers did this.😢 Bloody Idiots.

What the bulb number

I broke the plastic cover lens on the front dome light and cracked it.. it was literally so tight and wouldn’t come out 😭😭 Idk what to do now. I think I have to buy a whole new unit just to replace that 1 singular plastic cover lens and they’re expensive. If yours is hard to take out too, I would just leave it alone it’s not worth it !!!

You know if I can do the same with a gla 250 2018?
