My "passenger air bag ON" lights turns off when headlights turn on?

[Henry_mak16]

I barely noticed that when I have a passenger the airbag on light comes on the side, then it goes away when I turn on my headlights. Is this a safety hazard? Will my airbag not deploy if my headlights are on? o.o Leggo yaris world I'm scared!!

Turns off or just goes dim? Do you have the dash lights dimmer turned down too far?
