risbe (v trojniku) z dovolj podrobnostmi za določitev tipa, ki prikazujejo geometrijski položaj, v katerem je treba svetlobno napravo vgraditi v vozilo, os opazovanja, ki naj velja kot referenčna os pri preskusih (vodoravni kot H = 0°, navpični kot V = 0°), točko, ki naj pri navedenih preskusih velja kot referenčno središče, navpične in vodoravne tangente na svetlečo površino in njihove razdalje od referenčnega središča svetilke.`
drawings (three copies) in sufficient detail to permit identification of the type and showing,geometrically, the position in which the device is to be mounted on the vehicle, the axis of observation to be taken as the axis of reference in the tests (horizontal angle H = 0°, vertical angle V = 0 °), the point to be taken as the centre of reference in the said tests, the vertical and horizontal tangents to the illuminating surface and their distance from the centre of reference of the lamp.'
