Slmjim, appreciate the request for information, otherwise I might have never looked. The H4 housing/shell is labeled CPI. It has a Fresnel type pattern in a semi triangle shape extending from the center logo towards the right (left from drivers orientation). It is marked Motorcycle also as you mentioned.

Yep, that's it.  Thanks for the response.  And, when we wrote 'right'  we meant the other right... .  That pie-shaped portion is left-side beam cutoff.

We've upgraded all our Z1's to that CPI H4 halogen headlight assy. over the years & saved working sealed beam headlights for shows if desired or box-stock necessity (looking at you, Barber).  The CPI's work fine with standard 60/55W H4 bulbs when aimed right, and H4's are ubiquitous, very robust & cheap.   The original Stanley sealed beam units that were OEM on Z1's, that also still have both filaments working seem to be made of increasingly-expensive unobtanium these days.

Good Ridin'
