[urq] H1/H4 Glass Lens compatability

[Frank de Kat]

Hello All:

I'm wondering..

As far as I understand, regarding the H1/H4  Glass Lens:

-Hella & Cibe of the same type lenses are interchangeable

-Right hand and left hand drive lenses (Think North America vs 
England) are interchangeable


What I don't know:

Are the old style 'flat' lens and the newer 'sloped' lenses 
interchangeable, regardless of the reflector housing behind them?

(Say.. Did anyone else hear that Marc Swanson has just recently 
obtained a urq?)
