Hello. I don't know the model of your car, but & nbsp; I also had a headlamp problem in 206. The lamp was constantly on when it was in the position that should normally be lit when the doors were opened. There was also a problem of flashing from time to time. I removed the lamp and cleaned the inside. I think there is a metal part that completes the circuit, it falls under the on / off button. There was a sticky liquid wiped with a dry cloth on the metal part. As if there is no problem for now. The doors light up when they open, and when they close, they flash when they open the door lock. Mine was done inexpensively. I hope yours will be & nbsp;
