Simple upgrade of original non-tinted exterior mirror lenses.
US and Australian specification .:R32's came standard with non-tinted exterior mirrors in the larger 175 mm size mirror casings.
Some earlier Golf's were supplied with blue tinted lenses to reduce night time glare from the headlights of following traffic.
I also took the opportunity to convert the driver's side lens to the aspherical design from the flat (yes, flat!) stock lens.
