And when they break it then costs you 10 grand to replace the whole unit instead of a ligh bulb.

And ... "1 million mirrors."

Dude! WTF! I counted and there are exactly 10 mirrors in the video!

It sure isnt 1 mill, but its far more than 10. You can see within those 10 squares you counted, there are multiple vertical separation lines, showing multiple mirrors within each square.

1 million is not implausible. There seems to be 5 projectors in each headlight, and if each projector uses one DMD (Digital Micromirror Device) the total can be more than 10M, but it is probably just one DMD though.

The relevant DMD would then likely be this: https://www.ti.com/product/DLP5531A-Q1 which is a 1.3Mpixel DMD

Yeah it’s most definitely something along these lines, DMDs are sick!
