Your commentary could do with some work I think - you just told us what you were doing, but we could see what you were doing. We could have done with which lights were which, indicators, highbeam, lowbeam, how the led's are so bright, how the lenses work, what the motors do, etc. Ingineerix channel is very good at this!

I got hit in a parking lot to the front bumper, left fog lights and headlight enclosure all suffered (M3 LR 2019). I hope when they do the fix they will install these new matrix headlights. Hopefully it's possible.
Geez that is one complicated headlight. I own 21 MYP and not looking forward to having these go bad. Wondering if they sell parts for it like DRL. Appreciate archaic headlights on my other cars. All bulbs are replaceable
@gftgrill Do the turn signal LEDs look like they can be controlled individually? E.g. for a dynamic sequence turn signal? Or are they all connected in parallel?
connection in parallel will allow you to create a sequential circuit to control each of the inputs on individual leds. You’ll just need to control them via software with probably an arduino. Tesla’s control unit for these leds aren’t programmed to do such a thing.
was the outer projection lens glass? sounded like it. interesting design on it for being glass. cant imagine hella using plastic in the projector as it would eventually melt or distort
Its PMMA lens, only the smallest lens is glass and the other two are of plastic, it doesn't melt, great engineering efforts were put down for thermal managent.
No, there are only 3 wires going into the light. I believe it is software controlled through canbus. If you are able to intercept and decode the signal, then it might be possible to disable the turn signal. otherwise there is no physical way to do so.
So basically its got a 'low res' matrix array. If you look at most other makes their beam pattern don't have the same issue. Mercedes' Multibeam is a nice comparison
@@nazhif1 yeah you’re right, it does have a lot of light passing through and it looks interesting. It’s a hella design for which they say themselves they don’t have to make different projectors for different markets (only have to adjust something in software). Apparently it must also be DOT compliant, which I wouldn’t think when I saw it
it‘s 102 pixels for each headlight. As a comparison my current car has 16 on each side for the adaptive high beams and it‘s working great with that low amount. I believe Polestar 2 has 84 on each side. So it‘s not really low res, they just chose to make the cutoff lines really hard by not diffusing it further like on the Polestar 2.
@@t0n4us polestar may has less LEDs but my theory, looking and the beam pattern and behaviour, it only does horizontal matrix if that made sense…. So there’s only 2 rows of LEDs one for low beam and one for high beam thus there’s more effective resolution for the polestar. That’s why when it blanks out part of the beam the tracking looks smooth The Tesla meanwhile is doing both vertical and horizontal matrix that’s why you see more rows of LEDs but it does mean lower ‘resolution’.
@@nazhif1 Don‘t quite get what you mean, but the whole difference is the optics here. On my current car it‘s way way smooth on the edges because the beam is defused and slightly overlapping. Tesla could also make it more smooth by just partially enabling the LEDs at a lower brightness at the edges (same thing antialiasing does in 3D rendering) - but that‘s either not possible or they wanted maximum brightness up until the edge of the allowed beam pattern. EDIT: If you meant that the polestar only has 2 rows of LEDs, nope. It has 3. almost the same pattern as these headlights here. You can check it out on the official polestar 2 page, there is a video with an explosion animation of the headlights.
There are a lot of points of failure, each requiring replacement at around $1500 per lamp. Why didnt you heat the lamp to melt the glue and open it without destruction?
As a rookie engineer I would state that this design is not optimal - not revolutional, not even evolutional. 2 grams of LEDs are on a PCB that is 200x larger/heavier. Plus bulky connectors that are prone to corrosion. Also WTF, connectors?! for a product that can NOT be dismantled.
I assume in this case the PCB also has a function of cooling the LEDs, so there's no need of additional passive cooler. And harness must have option of disassembly to be able to replace the PCB or harness in production if its tested and not working. Without that option you throw away whole headlamp.
All this is completely irrelevant if you can’t take the glass away from the case in a nice way so that you can replace it once you fix whatever’s broken inside.
There is a chance that the LEDs works for decades, more likely that a driver chip gives up. Can be all repaired by electronic guys, however swapping is less expensive.
@@raaah 50 years the headlights were made out of glass and with parts replaceable and perfectly waterproof, now they are made out of plastic and garbage parts and cannot replace anything so you can pay 10 times more for anything
Man you are so messy. No hard feelings but whole video was so violent. Cutting of the headlight un even. I'm car mechanic and my heart hurts when I see things like this...
I don't know what it stands for but the top motor looks like it steers the projector assembly left and right and the bottom motor moves both the project assembly and the reflector assembly up and down. A very fascinating mechanism.
AFS = Advanced Front-Light System: en.wikipedia.org/wiki/Headlamp#Advanced_front-lighting_system_(AFS) It is used to move the headlight beam up/down and left/right. this is helpful lighting during cornering and lowering the headlight to not blind oncoming drivers. Trucks use this so that when they have a heavy load, it keeps their headlights from pointing upwards.
This is correct. The projector tilts up and illuminates all the pixels when high beam is toggled on. And if you only flash high beam, it only illuminates all the pixels but doesn't tilt the projector itself.
The one question that I didn't see answered was can this entire headlight assembly be installed on a vehicle without LED matrix and work with a software update? Our '21 Model 3P was delivered during the changeover. There were literally cars being delivered the same day with the matrix setup and yellow rear blinkers. Is there different wiring to the headlights like there is on the yellow blinker rear taillights?
hello! I don't know the answer to your initial question but about the rear yellow blinkers, no model 3 has rear yellow blinkers. the model y has rear yellow blinkers and all model 3's are red. my LR M3 was delivered Sep. 27, 2021 and it has red rear blinkers and matrix headlights!
AFAIK the last projector you disassembled was the high beam. The single LED you mentioned in the end is actually 102 LEDs that can cut out oncoming traffic as soon as software and legislation allows for that.

I love the elegant and precise disassembly. Kind of reminds me of a wrecking ball.
I thought with the extreme precision dismemberment it reminded me more of a bundle of TNT with det cord.
What this video tells me is that if theres ever any problem with a headlight, its getting replaced not fixed...
the projector itself is a standard SSL 100 hella light module. other brands also use them so if one breaks you can find plenty of replacements.
Looks like benz ones.
Only problem I believe is these are sealed shut so you can't get inside to change modules in the first place without being irreparably destructive
Looking forward to re assembly🤗

Is it possible to disable turn signal without disassembling?
No, there are only 3 wires going into the light. I believe it is software controlled through canbus. If you are able to intercept and decode the signal, then it might be possible to disable the turn signal. otherwise there is no physical way to do so.
@@gftgrill thanks, I was afraid of that. My plan was to delete headlamp blinkers and solely use sequential fogs as turn signal.
