When a vehicle is parked at night on the shoulder of a through road with insufficient lighting, it must keep the **position lights** switched on, which indicate the presence of the vehicle. These position lights may be replaced by the **parking lights** if the vehicle has them, which serve the same function of warning other drivers. This measure is mandatory to ensure road safety and prevent accidents.
