What's the difference between the map light and dome light?

I have a 2003 Ford Taurus SES sedan. I want to put LED interior lights. I was looking it up and I has dome and map lights? So I looked up the difference and the only thing that kept showing was the overhead dome housing?

Dome light is in the middle and lights the car.
A map light points at the passengers lap so they can read a map.

A dome light is non directional and lights up the entire area, a map light is focused for the user to read without disturbing others in the vehicle.

I would say that the dome light is in the middle of the car to light both front and back seats, and that the map light is in the front, … For reading the map(?)

Alright, thanks. Well no one hardly uses maps anymore?
