Lighting problem

Hello, good morning.
I have a problem with the lights on my Toledo 1.6 petrol. When I went for the vehicle inspection (ITV), they detected that neither the headlights nor the reverse lights were working. Of course, they failed me. I've been checking the fuses and I've seen that they're not receiving power. Could someone tell me if they go through a relay? I've looked in the owner's manual, but it only shows the fuse locations. If anyone has any ideas, I would appreciate a reply, as I only have two weeks to take it back. Thanks and regards.

Well, thanks for reading the message. I've already solved it. In case anyone else has the same problem with the reverse lights, it was in the wiring near the trunk; the wires were cut. And the headlights were faulty; I replaced the switch, repaired the wires, and they're working now. Cheers!
