headlights stuck? the airbag lamp is on

There is a 206 model with LPG, sometimes there is a click sound during the stay, sometimes when it enters a hole in the pit, then the headlights come on, the airbag lamp is on, the horn does not press, in short, it crashes. the signal is not related to the headlight lever. Even if I pull out the ignition key when I stop the car, the headlights remain on. what is the solution to this please help please not be crazy ??????
