How do you say i turn off the lights in french?

The most common way to say "I turn off the lights" in French is:

J'éteins les lumières.

Here's a breakdown:

* J' is the contraction of "je" (I) and "éteins" (turn off).

* éteins is the first-person singular present tense of the verb "éteindre" (to turn off).

* les lumières is the plural form of "la lumière" (the light).

You could also say:

* J'éteins la lumière. (I turn off the light.) - if you are referring to a single light.

* Je vais éteindre les lumières. (I'm going to turn off the lights.) - if you are emphasizing your intention to turn off the lights.

The best choice depends on the context of the situation.
