not sure where that quotes from, no reference but this is directly from the good book.... "Vehicles equipped with High Intensity Discharge (HID) or LED dipped beam headlamps may be fitted with headlamp washers and a suspension or headlamp self levelling system. Where such systems are fitted, they must work; however, it is accepted that it may not be possible to readily determine the functioning of self levelling systems. In such cases, the benefit of the doubt must be given" http://www.motuk.co.uk/manual_170.htm regardless of what i says on the internet, the testers ALWAYS default to the manual....my old man whos been a tester since i was nipper says "if it never had any to begin with, theres nothing to test" this is true, failure is ALWAYS due to the beam being wrong...simple
