Downgrading headlights (how do I read LIN signals)?

[AndrewApple12]

I currently own a 2018 model s. The led headlights on it are terrible. ive had them replaced 3 times under warrant and the are still having problem. Teslas asking price for replacements is $3,298 and I didn’t want to pay for headlights that are going to fail again. I want to put in the pre facelift hid headlight. my only issue is that the car controls its current headlights with Using LIN, is there any way to read or conver it to just the basic 12v signals?

I will post updates on my project once I start.

I've managed to build a device to read VDFRONT LIN bus.
What I'm trying to do is to build a HomeLink device to open my gates, but I'm stuck with protocol analyze. Right now I can get LIN bus dump, and I see there messages to headlight that change when I turn on high beam (something like FF FF FF FF FF when evarything is on). I assume it's a control message for individual pixels and it can be used and decoded by ESP32.
I can share get the dump from my car (with lights on-off and a lightshow to identify TESLA pixels). But can anyone help me with dumping Homelink learning and interaction?

Wait, why? Why not wire a homelink (garage door) receiver to your gate?

Because I have a garage door that doesn't support homelink, and I don't want to by homelink adapter and then a new gate for my condo. And I have no access to the gates, and can't add something or connect something. So, anyway, I need to invent something to join homelink in the car and the gates

I was thinking you could just add a cheap homelink receiver to whatever gate and garage door opener you have. Looks like they are under $20 on amazon. How old is your garage door opener that it doesn't work with homelink? Mine is from 2001, still programmed right up.

I have no idea about my garage door age, I don't even know the model. All I have is a remote without any visible model signs that was given me by landlord. And, I have no access and can't replace or modify the gates, because many people use them.

And I don't want actually to interact with all of this, because it's interesting to build my own device.

If I fail, I just buy a homelink module sniff the protocol, and build my own 433,92 garage opener using my remote.

So, this is a sport, I was just looking for some other psycho, that like to sniff lin buses

I'd try to train it first, it might be one that the car can emulate without doing anything. I use $8 openers off amazon for my garage door. I think the protocol has been standardized for a long time. Or ask someone with a Tesla with homelink to test it out. Might just work with your existing stuff without doing anything.

I still need to buy homelink adapter for 350 Euro (and they are not in stock) though.

But yes, I would tried it, if I had easy and cheap way to get my hands on it.
So, I'd rather ask some with Tesla to get a dump, so I can spend one evening programming my own

But, for sure, if I had an existing adapter nearby, it would be much easier.
