I have lost both low beam lights , bulbs are good fuses are good, any ideas ?

 

This happens to me all the time. Driving and the headlights cut off but the brights work.
There is a relay in the fuse box up front. The same size is used for your fan clutch. Trade them out and see if your low beams come on.
I keep one in my glovebox and trade them out at Autozone about every 6 months. In a pinch you can trade the fan clutch but make sure you dont drive it long.
Duralast 20601 is the part number.
