the indicaters that go on the side of
the nose how high have they got to be from the road ?

My little diagram says min of 350mm from the bottom of the light. and max of 1500mm or 2300mm if impractical

and a separation of min 500mm or (400mm if vehicle is less than 1400mm wide)

There is also a minimum distance into the body from the widest point (back wheels).

Dont know what it is (perhaps 40cm?), but know i had to extend my little bike indicators to pass SVA (although VERY borderline)
