Parking lamps
Switch position 
: the vehicle lamps light
up on all sides, e.g., for parking.
Do not use the parking lamps for extended periods; otherwise, the battery may become discharged and it would then be impossible to start the engine.
When parking, it is preferable to switch on the one-sided roadside parking lamps.
