I was driving at night with brights on and i went to flash them off cause an oncoming car they wouldnt turn off (the brights stayed on wouldnt go to low beams) i tried several times then they wouldnt go on at all low or high beams....now my lights wont work at all but brake lights and turn signals still work.....can not find a fusebox for headlight....
I don't believe there is a fuse. There is a circuit breaker built into the headlight switch. If you are sure the headlight switch is good, it could be a bad dimmer switch. If you have a voltmeter, with the headlight switch turned on, a larger yellow wire going from the headlight switch to the dimmer switch should be a hot wire. The dimmer switch sends power on a tan wire to the low beams, and through a light green wire to the high beam bulbs.
If your high beam indicator on the dash also doesn't work, then it is likely one of those switches. A voltmeter or test light would need to be used to find which one is bad. If you can find the connector at the steering column going to the dimmer switch, pull it apart and check for power on the yellow wire coming from the headlight switch, with the headlight switch turned on. If no power, the headlight switch is bad. If there is power there, then the dimmer switch must be bad.
It could be the switch or the bulbs or the headlight relay.

first, make sure the bulbs are in good and snug, 2nd, make sure the wire harnase is plugged in snug.

Unless a car has been in an accident it is very rare that the adjustment of haedlights change. the usual problem as in your case sounds as if the headlamp is not installed properly. It is either loose or not seated properly. So check there first.
