My Astra Coupe Mk4 (2002) has just failed its MOT due to the headlight alignment pointing too far down. (It has passed two MOT's previously with these lights although I have had a slight knock to the front bumper which may have affected the alignment.)
I've taken the car to a garage who have tried to align them but say it can't be done.
I have to get this fixed asap without the expense of needing new lights. I'm sure there must be a way to adjust them? Any advice or help appreciated.
