I've wondered this as well as there are times where I feel the low beams aren't really going out that far in front of the car. Feels like I'm driving faster then the lights allow me to see if that makes sense
How to adjust the headlights has been covered a few times in the forum.
For example: http://www.mazdas247.com/forum/showthread.php?123830060-Headlight-Allignment&highlight=headlight+adjust
Ride92 I finally figured out what was wrong with my low beam 2016 Tech lights. The load sensing adjustment that lowers the lights when the rear is pressed down with a load was installed 180 degrees out of phase and was lowering the lights when empty and raising them when loaded.
This was done at the Mazda factory? Inexcusable! Good headlights are important, I can only imagine the negligent person who installed that backwards had no idea the danger and risk their negligence caused. I spend a lot of time in areas with no houses, no streetlights, no traffic signals and plenty of winter darkness. In other words, if there are no clouds, when people from the city look up, they are blown away. People who have never left the 24/7 glow of the city may not realize just how important headlights are to those of us who travel in truly dark (and often rainy) environments.
If Mazda had even one employee who was installing 50% backwards, even if only for a week, they need to send out recall notices. At least the proper installation can be verified visually without needing to remove anything (or even without putting the car on a lift). I imagine this explains a number of people who have complained of a cut-off that was too low. Good thing it's a simple fix!
On a side note, does the leveling also active on inclines and declines?
I didn't know the headlights were self leveling. I new they turned to "see" around corners but I didn't think moved up and Down at all. Il. Have to check the load In the back thing and see if I notice anything.
