Both technicians are partially correct. If none of the external parking and headlights turn on, it is possible the headlight switch is at fault. However, it could also be caused by a faulty circuit from the battery to the switch, as Technician B suggests. Further diagnosis is needed to determine the exact cause of the issue.
