Hi Richard,
I understand how simple it would have been to paint in matt black primer during manufacture, then to touch-up later when fitted. However, that does not explain the red primer underneath the matt black. I am not saying - all - lights were finished in this way but I have a couple of examples, which are Butler side lamps that have the smaller lens aperture with the blackout "shield" behind the glass. This "shield" has pinholes, so are really blackout side lamps. I must dig out the headlamps and check them as well.
Just another mystery to solve - it what makes this hobby interesting.
Cheers,
Dave
