pics of cibies vs. hella h1/h4's?

[auditude at neta.com]

I have various pics of ur-q's, and some of them appear to have 
better (to my eye) looking eurolites than others.  They are more of 
a faceted design, with a clearer lens.  These must be Cibie 
eurolites, then?

As a matter of fact, some seem to have one headlight looking 
clearer than the other.  I wonder if these are mismatched.  I would 
tend to doubt it, it's probably just the angle.

Could anyone post a link to a pic of some bonafide Cibie eurolites, 
perhaps one of some Hellas too for comparison?  Also, is it true 
that the lenses on Cibies are not replaceable?  Or is it that they 
are too expensive?

Thanks,

Ken
