I think this is from a loaf Westy but I am not sure. I have been asked to 
post this on ebay but have not done so yet. It's marked Hella on the lens and 
on the back it says:

Polirat�t beachtan 12 V 8 W

I don't know if it's the same as a Vanagon Westy but sure looks better than 
those white lens ones.
