This SAE Recommended Practice provides test procedures, performance requirements, and guidelines for front cornering lamps intended for use on motor vehicles.
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.
