what is the year make and model of the car you would like information on? do you have daytime running lights too? Do they work normally, if you do?

going off the wiring of a 02 grand am, the auto-headlamps works off an ambient light sensor on the top or your dash that goes to the body control module. If it sees it getting dark the BCM will turn the circuit on.

you could check the AUTO HDLP CTRL relay in the underhood fuse panel.
