Signal and Marking Light Sources
- Ground Vehicle Standard
Inserted 2.2.2 with references for UN Regulations 37 and 128 and UN R.E.5.
A cross-reference to SAE J2560 was added for halogen filament light sources suitable for signal and marking lighting.
Added the option of using IEC 60809, UN Regulations 37 and 128, and UN R.E.5 as alternate sources for determining filament, or light emitting area location.
Table 2A was expanded to include more typical signal and marking filament light sources for motor vehicles.
Table 2B was expanded to include new standardized LED light sources: LW2, LR3A/B, LW3A/B, LY3A/B, LR4A/B, LR5A/B, LW5A/B, LY5A/B, LR6A/B, L1A/6, and L1B/6.
Newly entered light source specification data was taken from U.N. R.E.5 and/or provided by light source manufacturers.
The definition of light center was harmonized with UN R.E.5, which is an improved definition that also adequately covers LED light sources.
The test section (4.3) for LED light sources was split between the legacy LR1 light source (present in the June 2011 issue of SAE J573) and the other new LED light sources. Test methods for all LED light sources other than LR1 are included through normative referencing to UN Regulation 128, UN R.E.5, and IEC-60061-1, where the newly introduced Table 9 provides the references.
The requirements sections for LED light sources (5.4 and following) are dedicated to all LED light sources other than LR1. Specifications and requirements for all LED light sources other than LR1 are included through normative referencing to UN Regulation 128, UN R.E.5, and IEC-60061-1, where the newly introduced Table 9 (Replaceable LED light sources and related dimensional figures) provides the references.
The existing requirements for the LR1 were moved to a new Section 6.
Introduction of a new Table 10 to provide a direct reference to UN Regulation 128 and UN R.E.5 for the thermal behavior of the luminous flux of LED light sources.
Existing tables were converted to a new format.

Lighting Standard Practices Committee
The Lighting Standard Practices Committee is part of the Lighting Systems Steering Committee that reports to the Motor Vehicle Council (MVC). The committee is responsible for developing and maintaining SAE Standards, Recommended Practices and Information Reports related to the general support of documents in other VESG committees that are related to exterior lighting devices used on passenger cars, light trucks, vans and multipurpose vehicles. The committee monitors the development of related technologies and determines how they may be applied to general practice documents while also working to support the development of standards to aid in the application of various lighting technologies. Task forces may be developed in the future to support these activities. The committee welcomes input from OEM¿s, suppliers, consulting firms, government, academic institutions and other interested parties
