Park vehicle approx 4yards from a wall or garage doors,switch on dipped beam,observe which way the 15 degree line or called kick up line points to,this kick up line needs to be straight,using a card or ruler
place over the lamp,moving the card you wii make the pattern straight,once this is done use gaffer or
insulation tape.this then should pass the test,the tester will note on the advice sheet headlamp masks
were fitted,or buy british spec headlamps,i hope i have explained this ok.
