The number plate light is in the same housing and has it's own holder and power supply cable within the housing. It is a 12v filament rather than a LED. That seems less prone to getting crimped and damaged than the tail LED lights supply wires. The LED's are on separate supplies, LH and RH and can blow separate fuses even if they short out, as I found out. The front sidelight is on the same circuit as the rear one.
