In the case of low beam headlamps that are designed to conform to SAE J1383, the luminous intensity from the lamp shall be equal to or greater than 40%, but not more than 100% of its designed photometric intensity values when tested at 1.5D-2R in accordance with SAE J575 or b. I

31、n the case of high beam headlamps that are designed to conform to SAE J1383, the luminous intensity shall be greater than 2000 cd, but less than 7000 cd at the H-V test point when tested in accordance with SAE J575.

32、t to Other Lamps If a DRL is located such that its lighted edge is within 100 mm of the optical center of a front turn signal lamp, or within 40mm of a lighted edge of the front turn signal lamp, it must be extinguished or its luminous intensity reduced to a maximum of 250 cd or less at the H-V axis

33、 of the DRL during the turn signal operation. The only exception is when the turn signal is already 2.5 times the required turn signal intensity level.

37、 at the same mounting height, and symmetrically placed laterally relative to the centerline of the vehicle; c. not higher than 864 mm above the road surface, in the case of a high beam headlamp whose reduced luminous intensity is 3000 or more candelas at any location in the beam. 6.9.2 Area Requirem

38、ents The dedicated DRL shall have a minimum unobstructed effective projected luminous lens area of 25 cm2. 6.9.3 Visibility When a DRL is installed on a vehicle, the centroid of the lens area through which the daytime running light function is provided shall be unobstructed and visible from any poin

39、t contained within the solid angle bounded by vertical planes 20 to the left and right of, and horizontal planes 10 above and below, the H-V axis of the lamp. 6.9.4 Light Source Operational Requirements The DRLF, if implemented by use of a filament lamp(s) operated at reduced voltage, shall be certi

41、ts. 7. GUIDELINES 7.1 Telltale 7.1.1 A DRLF telltale shall be located on the instrument panel or in the drivers forward field of view. The telltale shall provide a visual signal only when the DRL system is activated and tail lamps, side marker lamps, license plate lamp and front position lamps are n

42、ot activated. 7.1.2 The telltale shall emit light and have a minimum projected illuminated area of 18 mm2.

DRLF is provided by low beam headlamps operating at full voltage and all exterior marking lamps are activated together with the DRL system or b. There is an automatic photocell sy

44、stem switched from DRLF to night exterior lighting mode. If an automatic photocell system is used to activate the night exterior lighting mode, the light sensor shall activate the lamps when the ambient luminance is less than 1000 lux, on a horizontal surface, indicating dusk, night, or other reduce

45、d light conditions. SAE INTERNATIONAL J2087 AUG2017 Page 10 of 10 7.2 Operation These guidelines apply to how the DRL lamps are used on the vehicle and are not part of the requirements. 7.2.1 The DRLF is to be activated without any switching by the operator (apart from the ignition switch). 7.2.2 No

46、 other lights are required to be illuminated with the DRLF unless full intensity low beam headlamps are used as the DRLF. In this case, those exterior lamps that are required to be illuminated with the low beam headlamps shall be illuminated. 7.2.3 The DRLF is to be deactivated when the low beam hea

47、dlamps and/or fog lamps are switched on. 7.2.4 For vehicles equipped with start-stop engine operation systems; once the Daytime Running Light Function has been turned on, the Daytime Running Light Function shall remain on, during each engine off period of the start-stop engine cycle. 7.3 Installatio

48、n 7.3.1 DRL lamps should be spaced as far apart laterally as practicable and the dedicated DRL lamps should be mounted on the vehicle so the optical centers of the lenses are not less than 250 mm or more than 1500 mm above the road surface. 8.
