It is a light on a car. Turn on the car light. (that would be the light inside the car)

Or, you can use the possessive: Turn on the lights of your car. (that would be the headlights (plural) on the outside of your car.)

Are you agree with these? if so, I am confused with them. Would anybody please explain them, in a simpler way?

Many thanks

While I don't think your options are technically incorrect (though "lights of your car" sounds strange), to me the use of "car light" itself is ambiguous and I doubt I would hear it said that way.

It would be better to say:

Turn on the headlights.

And we say dome light for the interior light.

Turn on the dome light.

It's understood you are referring to a car.

  • A health warning: in British English I have never heard the phrase "dome light" and would not understand it, so perhaps use something like "turn on the interior light". Dec 31, 2014 at 7:35

You can say, referring to the lights that are part of the car lighting system:

  • the car's lights
  • the lights of the car.

Genitive Case

You should still use the genetive case when talking about things that belong to other things.
