This document was revised to incorporate changes to the new more user-friendly photometry format balloted and approved in June 2006. There are no photometry requirements changes to this document. The current Table 1-Photometry Requirements is replaced with Figure 1-Photometry Requirements and current Figure 2-Test Point Orientation is changed to Figure 2. Corresponding references to them in paragraph 6.1.5 are also changed.
In the new Figure 1 the area defined by: 10U to 90U¿45L to 45R is now identified as Zone 1 and the Note 2 scan is shown as "A scan shall be performed in 1-degree increments both horizontally and vertically. If any point exceeds 125 cd during the scan, a maximum of 500 cd is permissible if contained within a ±2 degree conical angle." which is the same procedure as currently in J583 Front Fog Lamp.
Also, the 4U, 2U, 1U and H-45L to 85R are identified as Lines 1, 2, 3 and 4 respectively and Note 3 states: "All-line scans are to be performed an lines 1, 2, 3 and 4 for maximum cd." which is also the same note as used in J583.
