I suggestion maybe.  Try another inspector/station
that may be less critical.  These arbitrary/subjective
inspections suck.  A few yrs. ago, my Dorf pickup
failed because my headlight lenses were "too yellow".
Apparently, the Lexan? yellows over time.  These
WEREN'T very yellow.  Second next time I tried they
passed.  2 yrs. later they WERE pretty yellow so I
replaced them.  Just something to maybe try.
