If anyone is still looking to retrofit Matrix LEDs. I did it on my 2018 3. I bit the bullet and decided to order off aliexpress after I came across what looked to be original. The headlights were roughly $400USD for the pair, shipped quickly, and they did a great job with packaging.
I got the lights and it has the original TESLA stamping all over and they work fine; the seller told me they were straight from the Gigafactory in China. I have not done a direct comparison with another matrix LED to compare the beam but I have had them for almost a month and no issues so far. I can post photos if someone is interested.
