Do you have access to a test light or voltmeter?
Check the low beam headlight fuses in the under hood fuse panel. If these fuses are good, try swapping the low beam headlight relay with one of the other relays in the panel. If the lights still do not work then it is likely the low beam bulbs that have failed. I have seen several instances of both low beam bulbs failing at the same time.
