Hi,
First of all I was at my city at Mazda service and they couldn't adjust my headlights!

I pulled out from bumber and fender the right headlight assemble and startred to play with screws.
At the bottom it moved the light up and down.
But at top doesn't move left/right or anywhere, I couldn't see a difference.
1. What should do that screw?

headlight assembly



Because I changed the bulb also on the left side I have some cold color and at right side some warm or neutral color, so it is easier to see at the wall where is which bulb's light

how I see


I found this picture elsewhere.

the theory


Based on the 3rd picture and the second one at left side it seemns I have a RHD headlight.
2.True?

At the left side I don't know. I have a kind of U shape.
3. Is that a LHD or a RHD headlight what I have on the left side?
