I know that the IVA manual specifies 400mm in from the widest part of the car for indicators and headlamps, but do they mean the centre of the light or the outer edge of the lens?

Any help appreciated.

mine a SVA was to the outer edge of the reflective area, i dought it has changed for IVA

Outer edge of the illuminated surface.
