Being seen is a legal requirement with numbers attached. Every lamp on the vehicle has a rule about when it must be lit and how far it must carry.
Three lamps, not one
Between sunset and sunrise, the headlamps, the rear lamps and the number plate lamp must all be lit. A dark number plate is an offence in its own right, because it makes the vehicle unidentifiable.
The same requirement applies at any other time when people or vehicles are not clearly discernible at 150 metres — rain, fog, dust or smoke. The trigger is the visibility, not the weather.
Where people lose the markWaiting for rain to be heavy before switching on. The test is whether you could see a person at 150 m.
