Have you ever tried modding a new DRL strip into the refresh LED headlights? One that doesn’t burn out like the OEM ones.
You just gotta keep getting them replaced by Tesla. I went through, no kidding, 5 headlights, and now both left and right are flawless (and it's been long enough that I am confident to say they're unlikely to burn out).
This is definitely an issue with QC with these headlights.
