Did you voltage at the applicable fuse and voltage at the headlamp circuits. Use voltage tester.

Also, in the diagram below, orange wire is hot all the time. When you turn on the headlamp switch, the brown wire goes hot/voltage and carries voltage to tail lamps.

Could be a problem with wiring circuit from switch to rear lites? You can check the brown wire at the rear for voltage?
