ok im trying to get my truck ready for an mot, and 1 thing thats worrying me is the headlight beam!!!!!
well 1 year ago it passed the MOT with flying colours and since then i have not adjusted the headlight beam..... BUT!!!!!! since then i have lifted my truck by 3inchs and plus the tyres are larger and give it another 2 inch lift.....
so basicaly the beam is point in the same direction but im sure it might be too high as i can see in other peoples cars when i drive behind them, and they put there fog light on to tell me 2 turn my main beam off, BUT I HAVENT GOT MAIN BEAM ON!!!!!
ok so is this still ok or am i going have to adjust them????? i no how to adjust them but wots the best way of me to tell how far to adjust them????
-
Mine is lifted 2" and I never adjusted mine. I believe that it's the angle of the beam that counts, not the height, but I could be wrong . . . . . :wink:
-
THINK! its the angle, as my 90 thats 6inches taller passes and the lights have never been touched, plus disco is 4 inch taller and also never been moved, but always passes the light test.
-
the height makes no difference at all as they raise the machine to match height of lamps then test beam pattern you should have no problems at all.

Never had an issue with my lifted vehicle. And just as an experiment I went out, turned on the lights of the RR and raised it 2" .. headlights did not auto re-adjust as you'd expect. Turning wheel left and right makes them swivel left and right so they are working ....

It wont make any difference on the angle, as the height is pre-set on the beam tester in a slider, has to be from measuring a sports car to measuring a disco light, would be worth giving the adjusters aspray of oil and a coouple of turns in each direction though, as some testers will do them there and then if they move and need it
