Fail (stop) light coming on

When you turn on the headlight sensor of friends, it may cause malfunction (stop light flashes). In the first place, I guessed that the xzenon headlight brain was malfunctioning, but when I turned on the headlight sensor and started the vehicle, the malfunction light went on but there was no problem with the headlights being on.

Anybody have any idea?

Is it my sibling stop light or the warning light in colored? Only the lamp warning light gives the warning that the car's brain thinks the lamps are not on. If it fits this situation, there is no point in my car, too, because the parking lamps use less energy than the regular yellow lamps, they perceive the sensors as if they are not on.

Well, there is a stop light in the area where the speed dial is located. It flashes.
