I got into a small fender bender and wanted to replace my headlight because the pin broke. The replacement was a different model that didn’t have the rear ECU like the original so I kept the old light but the turn signal didn’t work. I’m going to make sure I get the same exact model and reprogram it.
hi~~!The 20-year model 3 headlight is broken, so I'm going to replace it with a used one. I'm curious. Do I have to install the broken ecu on the used ecu? And can I check it only in service mode?
Thanks for the video. On my 2023 Y the headlight seems not to be properly fitted as there is quite a big gap at the top left edge of the headlight and the panel (kind of like what you were saying at 8:54, mine needs to go up a little more).
Just put a left head light in new light model 3 matrix light. Had todo the ecu update to get it to come on. Problem I have now is it is shining way high. Went to calibration it moves around as you hit the calibration but when it goes to where you can select left and right. Right one will move up and down but left one I installed does nothing will not adjust any ideas or help would be appreciated
@@Tlsz1_8331 No just replaced one matrix with new one. You can replace with matrix lights but must replace both at same time and do software update on them. ECU update for ecu on new lights.
Excellent video by the way, this will surely help. Was that all that was needed for the BMS portion of the headlight installation? Just need to go into service mode etc.? Also for another video look at your library but did you already do one front bearings on our Raul Drive long range model three?
Yes, that was all I had to do was push a software update. I have not done a video on wheel bearings. I started with cars from the salt region and none of those went smoothly there were curse words and throwing, so I couldn't post the video, lol. If the car doesn't have alot of corrosion, they are pretty easy. I just added the instructions here for you: www.reeldealev.com/diy-instructions
I have Tesla Model 3 2020 can I install the matrix? If yes I don't understand about ecu, I install new or old ecu? And the software? reinstall the software? Thank you very much for info and fantastic video!
I believe you already have to have matrix headlights in order to replace them with matrix headlights. The ECU on your old headlights will have to be transferred over to the new ones. Once installed, then you use Service Mode to reinstall the software of the headlights.
i changed my headlight with the same modular as the orginal headlight however the bottom part of the headlight doesnt work, same as the turn signal anyone know what this is ?
I had to replace driver side headlight, but the Iman signal don’t work and I’ve tried it on two different headlights. Is there something I have to reset on the computer and how do I do that?
Thank you for the video! I have a 2022 Tesla model y Performance, my driver side, low beam high beam light is not working, 1 - can I just replace the light bulb? 2- is it replaceable? or is it welded and sealed with the main complete head light assembly? 3- your video shows the bulb is attached with the ECU, so it’s a one piece welded with the ECU and the light bulb as one unit/ one piece? Where can I buy the ECU/ light bulb unit from? What is the best brand and quality as in up to date? at least as good as the OEM or better specs and lasts longer or with a life time warranty? Where can I buy it from, what should I be searching for? I tried searching in UA-cam and online, but not enough information, or clear picture about this subject matter! Thank you for your help again! and yeah, once I have the part, where can I get it done to have it installed? I’m in the Los Angeles area in California.
@@飛びこむ水の音古池や蛙 Thank you for both of your emails, your Facebook message, and your message on UA-cam, I have not checked Instagram yet however. The link for the headlights is in this description, but here it is: www.reeldealev.com/shop/p/matrix-headlights
Do you always have to reprogram the headlight ECU even if it comes from a same year model? Can I put the ECU from my original headlight into a used one and it’ll be good to go without reprogramming? My “brow light” is out on my passenger M3 headlight. Figured a used one would be cheaper than a $1,209 Tesla replacement.
Any ECU not from the car will need to have software redeployed, but it is easy now. Yes you can swap over the original ECU to the new headlight. I would avoid used ones as it may be minutes away from unsoldering the LED like the one you have has done. If you just need the DRL replaced check out this video: ua-cam.com/video/7NHQSsIBJUU/v-deo.html
Great video! I'm about to tackle this myself as I need to replace the passenger headlight. You made mention of a " headlight ECU swap" for the headlight. My current headlight has the lens cracked and broken but everything still works. Are you saying I should remove the ECU off the original headlight and install it on my used, replacement headlight? Thanks
@reeldealev lol I get it but what happened to simple times where ya pop the hood and the bulb was accessible. I do appreciate your step by step instructions but for the normal lay person to remove the bumper is insane!
Thank you! Your video saved me $1400 in a repair bill. Software reload info was priceless and made it possible!
Thank you! I love these stories, having the software redeploy option makes alot of things possible now! Back 3+ yrs ago we didn't have these luxuries!
Great job, I will continue to watch your videos. I have a Tesla M3.
Thank you! Much appreciated! We are started on focusing on more 3/Y content.
Nice work!
Thanks for sharing
Thanks!
Them rims are sick!!! 👌
After watching your video, I also replaced my car light today!! Thank you for uploading the best video~!!
Glad it helped!
Do you need to disconnect the battery before you change the headlight?
Drebisss 😂 good video, Chad. Thanks for helping people do their own repair.
Thanks buddy!! I try to bring a little humor to a DIY video, I appreciate the catch on that!
ECU?

Any one have any idea on how to fix my problem with new headlight I installed
Thanks for asking I would like to also know about calibration and service mode etc. after install
So new headlight I got was bad refund got new light works fine now
@@TNtreasurehunterhi if I understand what you said, you change the led headlight with a Matrix led headlight ? If so, i want to do the same
@@Tlsz1_8331 No just replaced one matrix with new one. You can replace with matrix lights but must replace both at same time and do software update on them. ECU update for ecu on new lights.
I wasn’t sure about the firmware thing. Thanks. It’s exactly like the service manual says.
You bet!

Thanks for the video. Am gonna do my on my own. My headlight and turn signal aren't working
Looking for an update. That’s my problem, and they gave me an insane quote of $1,700. Did this work for you?
@brayleecody8121 Yeah, thanks so much. Your video helped me to fix mine at home. Just in my garage 😊❤
Oh wow this must be universal because i received the same price quote @brayleecody8121
Awesome video, thank so you much!
Thanks for the comment, you are welcome!
It’s good but what about the sensor for bumper
If you remove the bumper, disconnect the wiring harness on the passenger side, otherwise this little movement is not an issue.
Ok thanks
Where did you buy the headlights I have the same problem

Matrix headlights work in model 3 with this reflective headlights?
Negative..

Remove the bumper just to change a light?
Yes, pretty standard across all auto platforms at this point, but it isn’t difficult!

Did you keep the same ECU? What is your order number?

Won’t update the ecu firmware on headlights any ideas?
What is your order number?
Bro to have to take your front bumper off to change a freaking headlight is damn near criminal. Smh shit is nuts
We aren’t working on 69 Camaros anymore, this is pretty normal now. It looks worst than it is, it is quite simple.
@reeldealev lol I get it but what happened to simple times where ya pop the hood and the bulb was accessible. I do appreciate your step by step instructions but for the normal lay person to remove the bumper is insane!
Most modern cars unfortunately require bumper removal to change out headlight assembly. My 2006 mazdaspeed 6 requires this process as well.
Was great mistake to by electric car.
It? A? Buy? An?
