Scope:

This SAE Standard provides a method for determining the Effective Projected Luminous Lens Area (EPLLA) of a lamp function using design analysis. This standard was created to clarify and address how to determine EPLLA with traditional and new technologies.

Rationale:

Scope Removed reference to SAE J3333 since that SAE Recommended Practice was cancelled prior to publication.

4.3 Updated section to clearly state that overlapping elements cannot be counted twice.

Figure 1 Removed unnecessary example.
