I've been searching for quite some time for NOS 3 bolt headlamps. They're fairly easy to find in used condition although it seems like there's always a clip or a rubber piece missing. After months and months of searching, I finally found a set.
I briefly pondered buying newer lights but I wanted the 'real deal' and, right now, I'm happy I waited.
They're super clean in the photos and I'm optimistic that they'll arrive in similar condition.
One more thing to scratch off the list of parts to acquire.
