Most signal and marking lighting devices have light sources (bulbs), which can be based on either filament or LED technology. To assure field replacement, it is important that light source types employed be readily available in normal service channels. This document defines the physical, electrical, and photometric characteristics necessary to achieve a proper replacement for popular types of signal and marking light sources. Some of the design characteristics in this document are listed solely for the sake of standardization and are not intended to describe the performance of lighting devices (lamp assemblies) on the vehicle. Halogen filament light sources suitable for signal and marking lighting are specified in SAE J2560. The following revisions were made: a Inserted 2.2.2 with references for UN Regulations 37 and 128 and UN R.E.5. b A cross-reference to SAE J2560 was added for halogen filament light sources suitable for signal and marking lighting. c 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. d Table 2A was expanded to include more typical signal and marking filament light sources for motor vehicles. e 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. f Newly entered light source specification data was taken from U.N. R.E.5 and/or provided by light source manufacturers. g The definition of light center was harmonized with UN R.E.5, which is an improved definition that also adequately covers LED light sources. h 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. i 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. j The existing requirements for the LR1 were moved to a new Section 6. k 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. l Existing tables were converted to a new format.
