The first one : no rear brake lights ...... it happened the day of the mot control....

I tried to adjust them but i wonder if there is an error with the orientation of the head lamp bowl :
The adjusting screws are located ( when i look at the lights from the front of the car to the rear ) at 3 o'clock for the lateral adjustment and at 6 o'clock for the vertical adjustment.
May be the vertical adjustment screw must be at 12 o'clock because in the actual location at 6 , i can't lower the light level...!
Am i right ?
