Anybody know where I can get a replacement headlight for a 1975 Z1, either replacement or a fit for purpose modern equivelent?
The bulb seems to have dropped out and is swimming around inside the glass. It looks like a sealed unit.

Michellavitch,
Also if you don't want to spend too much, a sealed beam unit from a second hand car spares will do, as long as the light unit is same diameter.
I had an older Nissin lamp in my old Z1A, no probs!
