Was Thunder turning on night vision?

How do I activate night vision on the Ps4 in War Thunder.

Does this work with every tank or only with certain ones.

And if there are only certain ones, which tanks (from the Germans) would have them

This only works with certain tanks and then you have to research it first. The Leo 1, for example, has that. I don't know what the key assignment for it is on the PS4. But you should be able to find out quickly in the settings.
