How To Replace 2014 - 2016 Mercedes-Benz CLA 250 Headlight Ballast

[@jamesgraham6235]

Hey Reynaldo, a big thanks to your video. I also own a 2014 CLA250. I had the exact same problem for the drivers side light, when switching the bulb to the other side it worked. I bought the replacement balast and now works like new. Your also right about the bumper, takes longest time and a pain in the ass to remove. But save bunch of money VS having the dealer do the work. Again, thank you for all you tips and tools recommendations super helpful!! James!!

[@ReynaldoVelasquez]

I’m so glad that I could help out! I hope you’re equipped to do this on whatever car you have…. It’s basically the exact same no matter the car make or model

[@marcusnite6370]

Was there any issues with the coding after you put the new lights in?

[@rebeccanash6153]

Dead ass saved like 4-500$ did it in under 2 hours,bet!👍🏼

[@ReynaldoVelasquez]

@@rebeccanash6153 yeah, it’s a life saver

[@mdotfella5524]

Did you have to get it programmed by Mercedes after you put the new ballast in??

[@ReynaldoVelasquez]

Not at all. Just a simple plug and play. If it ever goes out just buy another $50 ballast and replace. This is an easy 30 minute project… maybe if it’s your first time it may take 1hr if you’re being extra cautious.

Hi I have a gla 250, one of the dipped beams is out so i changed the bulb, didn’t work so I swapped the left ballast to the right and both headlights stopped working. I put the good one back and it was back to the same one off one on. Any ideas would be appreciated thank you

[@erikjimenez5225]

Nice video! My turn signal & LED daytime running lights are out on the driver side. Would you think that is a ballast as well?

[@ReynaldoVelasquez]

If it’s the LED XENON version you may need to replace the entire housing. eBay has them for about 600-800. A little pricy but that should fix the problem

[@FMeng]

Did you ends up solving the issue? My driver side daytime light, turn signal and HID all stop working

[@oneday2584]

@@ReynaldoVelasquez what would be the part number for a 2014 cla 250 headlight Assembly because my whole driver side lights aren’t working, thanks

[@charecesims2]

Thank you for sharing. Can you let us know where on Amazon you purchased the set from?

[@ReynaldoVelasquez]

Hi, link is in the description

[@danielresendez9153]

Is the ballast universal for both sides or would i have to buy a certain one for the passenger side?

[@ReynaldoVelasquez]

Universal. It’s the same on the driver side too. But just in case…. I made sure to search for “passenger” / “driver” side….. juuuussst in case

[@vtecmike]

Dumb question but how do you remove the power source clip!?

[@oneday2584]

Do you know the part number for your 2014 cla 250 headlight Assembly, i need to replace mine

[@ReynaldoVelasquez]

Hmmmm let me look. No I don’t but I’ll check real quick

[@ReynaldoVelasquez]

Hi, so just for you… I went to RockAuto .com (it’s a pretty trusted site) and searched the car. There are part item numbers there but I don’t know if they are specific to that manufacturer who makes the lamps. But the number was: MB2502224 for the HID / xenon type. And for the Halogen type : MB2502222. The prices for the housing are : HID $1184 and Halogen for $200-$400. I should also mention that I did buy Mine (HID /Xenon) used on eBay for about $600 it worked perfectly. All I did was replace the ballast and bulbs just in case. I hope this helps. But check out rock auto and ebay for sure. Let me know if you need help on anything else

[@arturoreinaovejero3879]

hola amigo, los faros de tu coche son full led o xenon?

[@ReynaldoVelasquez]

Mis faros son de xenon. uno de ellos salió. así que probé esa bombilla en el faro opuesto para ver si funcionaba, y funcionó. así que supe que no era la bombilla. Compré el balasto de los faros en Amazon. enlace en mi descripción

[@sayelatyani]

Does sometimes if you replace fuse light its work

[@ReynaldoVelasquez]

Never worked when I tried. See if the fuse is busted first. If it’s fine then it’s probably the headlight itself (ballast)

[@akmusic74]

Hi my friend, my cla 200 has the led light blinking, not the bulb, it is the same solution? By replacing the headlight ballast?

[@ReynaldoVelasquez]

If you mean the little “daytime running lights” the little eyebrow made of LED’s I believe you’ll have to replace the whole headlamp housing. You can’t just replace the little LED’s. You can find a good condition used headlamp housing on eBay for about $600-$800 depending on the quality. Or some third party aftermarket light housings for about $200-$400. Hope this helps

[@schleiflife8793]

Do you have any moisture in your headlight? Im only asking because that is what i believe is wrong with mine. But either way order the same thing as him and its only $40! bulb too

[@ReynaldoVelasquez]

@@schleiflife8793 no I don’t have any moisture in the clear housing. However… I once had a cracked headlight housing and water would leak into where the bulb was. It would short circuit the light and the inside glass would get foggy. I tried using clear plastic glue to patch up the holes. But water kept leaking in. Eventually I had to just replace a brand new housing, ballast, and bulb. But in this video… the only issue was a bad ballast.

[@lukasmartinkovic826]

Hi , mine 13's cla 220 have problem witj left headlight xenon is out , led is workin, can you help me

[@ReynaldoVelasquez]

Yeah, if you’ve already tried to replace the headlight bulb itself… and it still isn’t working… it very well could be the ballast. It’s an easy fix. Just a few screws and bolts to take the bumper off and the old headlamp.

[@jjaafar]

Is the ballast also the issue if the high beam is not working? There is only one bulb for this type of headlight assembly (mine is BI-XENON) and the bulb is supposed to act as low and high beam. MB Dealership suggested to replace the entire headlight assembly for $1600++ (surprise! wtf to that)...

[@ReynaldoVelasquez]

Yeah well, first replace just the bulb. That’s an easy $60-150 on Amazon or any auto parts store. (You’re right, the one bulb is both high and low beam. I believe there is a little moving flap inside the lens housing that opens up fully to allow the high beam) if the Bulb doesn’t fix the problem, replace the ballast… 99% of the time this will fix the issue. You only need to replace the entire housing if your housing lens is cracked allowing water to leak in… or if the “eyebrow” led strip goes out for the blinker and daytime running lamp. Also if the ballast doesn’t work, there is also an igniter that helps the ballast. You could replace that for about $50 too. But that has never gone out on me. It’s located right near the ballast on the housing. Hope this helps, and sorry for the long response. Ask if you have any more questions

[@ReynaldoVelasquez]

Also…. If the “little flap” isn’t opening inside the housing, allowing you to get a full high beam…. But the bulb is working… then yeah it may be that little flap inside that malfunctioned… but I would still look on eBay. I found a gently used headlamp housing for only about $600 including shipping. Works exactly the same. And just transfer your old ballast on to it… or buy a new ballast and bulb etc. hope this helps

[@jjaafar]

@@ReynaldoVelasquez , much appreciated your reply about inquire. cheers to that! my bulb is new, i got a new ballast (which I am yet to to replace). What is the igniter? Do you still what the part number is and where to get it? Thanks!

[@ReynaldoVelasquez]

@@jjaafar I don’t have the part number but the igniter is near the ballast once you remove the headlight assembly, you will see another silver piece of metal near the ballast. I believe that may be it. You can just google the part or on Amazon. It’s also a simple plug and play part too.

[@sampsonsampson314]

I have a Mercedes Benz c300 and the passenger headlight is foggy and has water in the headlight housing. Now the headlights fails to on, do i need to replace the whole headlight or just the ballast please. Get back to me asap. Thank you

[@ReynaldoVelasquez]

So that exact thing happened to me before. When the moisture would dry up it would turn on again. But eventually the fog shorted out the ballast. You can replace the ballast only… but eventually with the first rain, car wash, or early morning dew… it will eventually blow out your new ballast and headlight again. So yes You will need to get that housing replaced for sure. eBay had some pretty good used headlights for sale. Just make sure to look at the screw brackets on the eBay listing photos. Sometimes a bracket may be broken off the housing, where it’s supposed to install to fender area (if the car was in an accident before etc) Make sure it’s all intact (so your headlight won’t be loose or flimsy when you install it) and check out the lens for yellowing and scratches. Find the best one that makes sense for your situation. Hope this helps.

[@veselintonev9930]

Hi mate, I have a 2014 cla 250! Thanks for the video. My problem is that the led daylight light is not working and I get an error that the turn signal does not work, which is not true. It works, but when I turn it on it clicks like crazy in the instrument cluster, but it flashes completely normal in the headlight itself. One thing to note is that when I lock/unlock the car it did not flash. My high and low beams work perfectly. Just the daylight led is not working. With your help I managed to replace first the balast on the bottom of the headlight, but nothing changed. Then I changed the control module which is on the side of the headlight/there was moisture inside/ and now the turn signal flashes when locking/unlocking the car. However, the daylight led came on only for a few seconds and went out again and does not work... I can see the following error codes when I scan with OBD: B177887 and B283F87. It's for the right headlight, left one is working perfect. Also, there has never been any water inside the headlight itself. Do you have any suggestions? Any help is appreciated!

[@MrMrxoblivion]

I have the exact same issue as you described...did you get any further or have any more information??

[@almightytgc6028]

hey, i own 18 cla 250 i change the halogens headlights to led headlights and when i be driving the turn signals stop working

[@ReynaldoVelasquez]

How weird. But I’ve been wondering about converting headlights back and forth into LED’s and halogens. As far as the blinker… it might be a glitch if that bulb blew out, or if you have the LED eyebrow then you may need to replace the whole headlamp housing to get it to work again

[@Princess-Myrealname]

What brand of led headlights worked for you? I

Hi, my passenger side headlight got wet from cleaning the engine, blew the bulb and replaced the bulb and still will not working, also was causing the led strips to not work until I put a new head light bulb in, once I’ve done that the led lights worked again but head would not, could this be the ballast too?

[@ReynaldoVelasquez]

It could be the ballast. There’s also another computer module right next to the ballast that I suspect controls the led strip. I replaced both and they worked again. Also another thing to consider is if water is getting into the clear headlight housing… it may look foggy like condensation is trapped in there… if that’s the case you may need to replace the entire housing, I found good used housings on ebay in good condition. The ballast and other module are only about $50 or so on Amazon. Hope this helps a little. The only way to know for sure is to replace the ballast.

[@kodyrice10]

What size socket

[@ReynaldoVelasquez]

Probably a 10 or an 8

[@toxictoons1374]

How did u unplug the power source plug from the light.

[@ReynaldoVelasquez]

You just pull the plug straight back. You may need to shimmy it side to side until it frees itself from the headlamp

[@toxictoons1374]

@@ReynaldoVelasquez gracias👍

[@mocosito01]

@@ReynaldoVelasquez I am having a hard time unplugging the power source and I am afraid to damage it. Does the clip need to be pulled in order to pull the power source out? too bad I cannot add a picture here

[@ReynaldoVelasquez]

@@mocosito01 yes the plug just pulls out. It may feel hard at first but if you shimmy it apart or use a screw driver to pry it apart, it will get easier. It’s just a really tight fit
