[OT?] H13 and HS5 halogen lamp. . .

[Starflex]

Hello!
Well...I'm searching the datasheet of a lamp, the H13.
In particular, I need the dimension of the socket,because in the sheet E/ECE
324 there isn't explain (in my opinion) in conprensible way.
Moreover, does anyone know a manifacturer of "HS5" motorcicle lamp?
I haven't found anyone!
Thank you a lot, and sorry for my poor english!
