4.1 The luminous intensity distribution requirements of front position lamp, rear position lamp, brake lamp and turn signal lamp refer to Figure 3. The numbers at the intersection of the grid lines in the figure are percentages, which represent the ratio of the minimum luminous intensity in that direction required by this standard to the minimum luminous intensity in the direction of the reference axis. The corresponding numerical requirements are listed in Tables 1 and 2.
Within the luminous intensity distribution range (Figure 3), the light emitted by various devices should be uniform, that is, the luminous intensity measured in any direction within the range surrounded by the grid lines shall not be less than the minimum luminous intensity value in the directions around that direction. These values ​​are specified in Tables 1 and 2. FO

Where: B, and Bz—the brightness of any two measuring points, cd/m2; B. - Minimum luminance of the measuring points shown in Figure 2, cd/m2; L—distance between B1 and B2, cm.
4.5 The installation of the rear license plate lamp should make the light incidence angle at any point on the surface of the illuminated area not greater than 82°, measured from the extreme position of the illuminated area farthest from the surface of the license plate. If the device has more than one lighting optical unit, this requirement applies only to the relevant part of the lighting area illuminated by the relevant unit.
