Perhaps you turned on the interior lights when you were adjusting the headlights?

Put the dome light switch on door located on the headliner to the side of the light
The door jamb switch normally completes the power circuit to the dome lamp when the door is open. When the door is closed the switch opens the circuit, removing power from the dome light. If the switch is dirty, defective, stuck pushed in, or disconnected from the wiring, when the door is open the switch does not close the circuit and the dome light remains off as if the door is still closed. The headlight switch provides an "alternate path" to close the same circuit and allow power to the dome light. I had the same problem on a 1997 Chevy C1500 pickup truck.
Check Your Door Switch, When You Open The Door The Switch That Is In The Door Jam, It May Be Stuck, Or Bad. Open Your Door Press The Switch Several Times To See If The Dome Light Comes On. It Also Could Be Bad. This Will Cause This Problem Also. Good Luck

The switches for the dome light on each door of a 2004 Olds Alero are at the front of the door. They are on the door frame where the door meets the frame when it is closed.
