i have got a 172 mk2 and my headlights are shining really low, i have done a search and found that im not the only one to have this problem. i have had a quick go at turning the white screw behind the headlight but it didnt look like my lights moved and i wasnt sure if i was turning it the correct way. could anyone tell me if i should turn it clockwise or anticlockwise to raise them. cheers
