The bulbs themselves have specific IDs - H4 is the three prong hi/lo 
used in a lot of eurolights, and the lenses available for retrofit in 
old sealed bean systems.

H1 is a high beam only bulb.

The crappy US lights these replace use bulbs like "9004", with an awful 
filament arrangement.

I guess you don't need a deep tutorial here, nor to I want to write it.

But bulbs have "one number".  Lenses, on the other hand often have two - 
the two bulbs that are used in them.  My 90Q lenses are "H4/H1" in that 
sense.

My coupe's twin 5" lenses alse use H4 for hi/lo and H1 for hi only. 
Quite convenient.

My Chubby truck uses 7" lenses running H4's only.  Or, at least, it will 
after I deal with the stupid plastic stuff around the connector that 
interferes with installation.  Hmm, and I might put H4's in the plow 
lights one of these days, too.

And as someone else pointed out, go to Daniel Stern's site.
