This may be a bad headlight switch or it may be a drl module if you have daytime running lights check headlight switch first check the brown wire see if power is still going to it after switch has been turned off. It may also be your warning module but check the brown wire first as that can cause warning module to ding like it is. You'll have to get tit scanned to see if modules are problem.

Check body ground from battery and eng/battery grounds then otherwise unhook warning module and see if lights go out. If they do your module may be bad or something is powering it up like a melted harness etc.

There's a white plug and a black plug. Unplug the white plug and the dinner went off and the lights went off.
