Passing beam and driving beam complete failure

Evening together at the streetka of my girlfriend the front lighting has failed, except the floor light that works. – quite great when it gets dark so early the streetka would have to have 2 different lamps for dipped and driving light?! Therefore I exclude a defective of the lamps. My guess is with a relay as fuses are all i.o.. Since the operating instruction has got wings, the question is, where is the relay box and which relay exactly is for the beleuchtu ng responsible I am grateful for every tip
