3.5 Reflectors—In this standard, reflectors are defined as reflex reflectors (SAE J594) or reflective material that shall be visible at night from all distances within 600 to 1 00 ft (1 82.9 to 30.5 m), when directly in front of lawful lower beams of headlamps. Reflective material shall meet the durability requirements for such material as specified in SAE J943. 4. Lighting And Marking Requirements
4.1 Lighting and marking for equipment defined in paragraph 3.3 shall include the following:
4.1 .1 At least two headlamps conforming to SAE J95 and mounted at the same level and as widely spaced laterally as practicable. Lamps projecting a trapezoidal light pattern and mounted at a height of 7 ft (2.1 m) or less shall be aimed so that the top of the beam is at least 1 deg below lamp center level but not more than 4deg below lamp center level, and centered laterally. Such lamps mounted above 7 ft (2.1 m) high shall be aimed so that the top of the beam is at least 6 deg below lamp center level and centered laterally. Lamps projecting a general flood pattern of light shall be aimed downward to provide illumination close to the machine.
