    I do have the auto sensor and the turn-on switch, which I leave in the same position. My low beam lights go off and on during the night time. When they go off, I have to use my fog lights in order to see where I'm going. Then ramdomly they come back on or go off again.

    will they come back on if you turn switch to on position? If not try changing the headlight switch, other than that sounds like a loose wire or bad or loose ground...Also even though they may have been check the head light relay may be faulty, it could work for a while but loose connection as it heats up, pull the relay and chen the socket carefully if socket looks good then try replacing the relay...

    Dimmer or multifunction switch is a good suspect! A "very good" suspect!!
