Our 2016 CX9 LED headlights are good, not great. Our 2017 Prius Prime LED headlights are better. I know that Mazda put better headlights on cars to other nations, but in the U.S. the old federal regs didn't permit the newer tech lights at that time. I think the regs have changed, but I don't know if Mazda has upgraded the headlights on this 2nd generation CX9.The LED headlights on both the CX-5 and CX-9 are downright fantastic.
This is a picture I found, but the screw is like this park about a car distance from a wall with headlights on. Open hood and look for a joke with a screw like teeth marks. Looks something like this move 180 degree at a time and you will see the line move line both side to top cut off lineI’ve seen people mention tilting them up. Does the dealer have to do that?
