My headlights stopped coming on all of a sudden

I have seen both low beam bulbs burn out at the same time.
Its possible the relays have burnt out for the low beams.

What make model an year vehicl ?

The fog lights on most vehicles sit directly underneath the headlight bulbs. The ballast and wiring work just like the headlights, so changing them takes not much time. The procedure to change the fog light is as follows:-- 1) Open the hood and reach down underneath the headlights to unplug the electrical plug from the fog light assembly. Squeeze the top of the release tab and pull the connection off the bulb's ballast. 2)Turn the fog light counterclockwise to remove it from the fog light housing. 3)Install the new fog light bulb.Then connect electrical plugs properly. 4) Test the fog lights by turning it ON. Thanks. you can rate this solution and show your appreciation.

Sounds like possibly the ignition switch is going out. Try jiggling the key in the ignition in the on position and see if your lights come back on.
