ANGLE OF INCIDENCE
The manufacturer of the device shall specify the position in which the device is to be fitted in relation to the space for the registration plate; the device must be so placed that the angle of incidence of the light on the surface of the plate does not exceed 82č at any point on the surface to be illuminated, this angle being measured from the edge of the illuminating surface of the device furthest from the surface of the plate. Where a device incorporates several lamps, the foregoing requirement shall apply only to that part of the plate intended to be illuminated by the device concerned.
