I took delivery of my model 3 on December 30th, 2020 and has the new headlights. I actually unmatched my VIN twice to make sure I had the new headlights. Another member on here figured out when the new lights were being delivered. Last 6 of the VIN begin with 871xxx and higher will have the new headlights. We have analyzed many VINs and this seems to be very accurate. My VIN is a 872xxx and has them.
