Sidelights are illuminating on the one side SSANGYONG REXTON (Y400)

I arrived, switched off the car and turn off the central locking system with the button on the key and went home. After a couple of hours, I looked out of the window and saw that the sidelights on the driver’s side were turned on. I looked at the front of the car and saw the same thing that one of the DRL was turned on from the driver’s side. I open the car, the “wheel” was turned on in the car, I turned it to “off” and the sidelights blinked off. Closed the car and the sidelights didn’t illuminate. What was it? I read on the Internet that there is a feature of  Opel if you switched off the car with a turn signal turned on, then the sidelight can light up on the side where the turn signal is turned on. Perhaps the same thing has happened with my car? But I didn’t touch the turn signal after I turned off the light.
