This is the light beam hit on the side wall "passenger side".
As you can see on the picture, what do you think is inside the red circle? What is the shadowed line? What is the problem and how it can be solved.

 

Check to make sure the bulb is seated properly.

 

Just out of curiosity, did you check to verify the opposite side doesn't have the same pattern display?

 

The opposite side is clean

 

Thats wried. Try switching your left with the right bulb and right with left. If it moves to the other side, its the bulb. If not, its some imperfection in the headlight.

I'm also curious in your garage floor, is it common in Bahrain, to tile garage floors?

 

I hope it's the bulb and not anything else, I will take it to the dealer since the car is still under warranty just to record the case but not repair, I don't want them to mess with the car, sometimes I don't trust their quality of work. Then I will try to switch the bulbs as you suggest when I plan to replace the bulbs with LEDs.

BTY, you hardly find garages without tiles in Bahrain these days
