What must be constantly operative on a motorized bicycle?

On a motorized bicycle in Germany, certain lighting and safety devices must always be functioning while the vehicle is in use to ensure visibility and safety. These include the permanent dipped headlights, which help you see and be seen during low light or nighttime conditions. The rear light is essential to make your vehicle visible from behind, especially in darkness or poor weather. Finally, the rear reflector provides passive visibility by reflecting the headlights of vehicles approaching from behind. All three are legally required to be constantly operative to reduce the risk of accidents. This rule helps protect both the rider and other road users.
