This SAE Standard provides test procedures, requirements, and guidelines for a daytime running light (DRL) function.
This document was revised to incorporate changes to the new more user-friendly photometry format balloted and approved in June 2006. There are photometry requirements changes to this document. The current Table 1 – Photometric Requirements is replaced with the new format Figure 1 - Photometric Requirements for a Dedicated Lamp Providing the DRLF (Function) Having Effective Projected Luminous Lens Area of 200 cm2 or Less, Figure 1 will allow closer harmonizing with the ECE DRL. Table 2 - Photometric Requirements is replaced with the new format Figure 2 Photometric Requirements for a Dedicated Lamp Providing the DRLF (Function) Having Effective Projected Luminous Lens Area More Than 200 cm2. A Figure 3 - Photometric Requirements for a Turn Signal or Park Lamp Providing the DRLF (Function) has been added. This gives an alternate solution for Turn and/or Park functions, and is referenced in CMVSS 108, paragraph 47, as SAE J2087 1991 Table 2. In Figure 2 and 3 the HV value remains at 500 cd to harmonize with Canada and their latest updates to CMVSS 108 Which made reference to Table 1 in 6.2.1, SAE J2087 MAR2006, will be replaced with Figure 1 and reference to Table 2 in 6.2.2, SAE J2087 MAR2006, will be replaced with Figure 2.
The Lighting Identification Code has been updated to allow all marking codes from U.S. and Canada, as well as the SAE and ECE codes.
