KeesSmit napísal:Hello David,
Regrettably, I have never seen an original T 77a with its original central headlamp still intact, so it is just speculating.
The text of the T 77a suggest that either the reflector was slightly off-set to the left (meaning that the central headlamp in both positions illuminated the left) Theoretically, the reflector also could operate diagonally, illuminating the left in one postion and the right in the other one.
This might be true - if the reflector operated diagonally, it could have been used to beam the light to left or right. That would also fit within the question, that I stated in my first post here.
As far as I am informed, cars in cities were only allowed to use dimmed lights or even only city lights.
Maybe it is just a confusing czech term "zacloneny", which is more like "covered" than dimmed. I was just wondering, why the lights have to be "covered".
You don't have to translate the Czech texts as I understand the T 77a one. I am only curious if the T 87 text is saying something different than the T 77a text.

, text about the T87 central headlight: what is written there is, that the central reflector has a wide beam of light. It can be either pointing straight ahead, or be pointed down to beam "under fog" not blinding the driver. Changing of lightbulbs is done by dismounting the headlights.
Btw, The 1948 Tucker Torpedo head a central headlight that moved with the wheels. On later Citroen DS, the inner headlamps also moved with the wheels.
Does anybody have the BMW text?
On the DSF, they were talking about these two vehicles too, just after Tatra. But I don't have it recorded
