Hi
If you have the normal Lucas PLC type switch, it contains three separate sections: Charge rate switch, Lighting switch and Ignition switch.
The only things driven by the Ignition switch section are the Ignition, The Ignition Warning Lamp, The Petrol Gauge, the Stop Lamp and the Trafficators
It seems unlikely to me that there is a simultaneous fault in more than one section which would cause the lights to be inoperative, though anything is possible. The ignition section is internally less "chunky" than the other two and therefore less reliable after 80 years. I suggest you carefully check the wiring before condemning the switch.
