In Europe we do not have the small bumpers near the repeter. Hence a larger repeater lens.
I have have the clear ( = white ) lenses instead of the stock orange repeaters ( front + side )
They are specifically made for the 911 "993" but will fit quite well. The result is very good, a non expert won't see any difference.
This transformation is very common in Europe ( 993 and 968 ) because the car does look more recent once equipped.
Like somebody said, real clear lenses for the 968 don't exist and have never been made.
I bought them on Ebay Germany ( they send worldwide ), and they come with the amber bulbs.
