Do I need to turn off the lights when filming at night?

First of all, I will give you the common modes of polaroid under popular science.

House mode: the flash is the strongest, and photography is carried out indoors or in the dark outdoors (at night).

Cloud mode: flash is the second, and photography is carried out under rainy, cloudy and shady conditions.

Clear mode: flash, shooting in sunny or slightly cloudy light conditions.

Sunny mode: the flash is the weakest, and the sunny photography is very bright.

Some cameras can also use hikey beauty mode: it is best to use it indoors, cloudy and at night, because it will have the effect of overexposure and dermabrasion, and if it is sunny, it will lead to overexposure.
