Checking the status
Check if the fault is permanent or intermittent by switching between high and low beam.
If the left xenon lamp does not switch between the high and low beam it means that the fault is permanent.
If the left xenon lamp switches between high and low beam it indicates that the fault was present previously but is no longer active, intermittent fault.
