If they're fitted ex-factory they'll actually have to change legislation to allow it.Same thing happened with Volvos when they ran the lights up the rear pillars, as previously the legislation didn't allow it.There are also some provisos in VIRM that say if there is something contrary, but fitted as OEM, it's allowed. The ST1300P has LEDs just above the indicators in the mirrors from factory, but the ST1300 doesn't.
