WWII-era?
No
Porsche 597 Jagdwagen?
No
Steyr-Puch Haflinger?
No
Trabant 601A?
Yes, locked for you to name the device.
I thought blackout headlight covers is the device.
Anyhow, is Tarnkreis or Tarnscheinwerfer the name you're looking for?
You found the purpose of the device. All I need now is its name. To help you a bit, it is a three-letter two-digit name, the letters being an abbreviation for a German word for the purpose (not Tarn... anything). Still locked.
Unlocked
Is it NMA-74?
Yes, it is the Nachtmarschanlage NMA-74, meaning night march device.
