I am not an mot tester ,but I am confused as to the regulations regarding non standard fit xenon headlights.I visit numerous workshops daily and get conflicting reports as to whether these lights need wash/cleaning system and auto level for a pass.Some stations are categorically classing this as a fail,if not fitted,and others are selecting pass and advise.Can any one here clarify the situation?I could be re-instating cars back to normal halogen lights for no reason!Good work while it lasts.
