During twilight or the hours of darkness, when must you have your side lights switched on as a minimum requirement?

In Germany, side lights (also called parking lights) must be used when your vehicle is parked on the hard shoulder outside built-up areas during twilight or darkness. This rule helps ensure that your parked vehicle is visible to other drivers in low-light conditions, preventing accidents. However, while driving, you generally need dipped headlights at dusk or night, except in well-lit areas where side lights alone are not sufficient or appropriate. So, the minimum requirement for side lights during twilight or darkness specifically applies to parked vehicles in unlit, non-urban settings.
