MIL-STD-1179 Lamps, Reflectors And Associated Signaling Equipment For Military VehiclesThis standard applies to all military combat, special purpose and tactical transport vehicles, both tracked and wheeled. Administrative and commercial vehicles are not within the scope of this standard, since total compliance with Motor Vehicle Safety Standard MVSS No. 108 is required for these vehicles. Infrared secure lighting photometric requirements apply to new military vehicles starting with serial number 1 manufactured after September 1, 1988. Retrofit, rebuild, or other modifications of military vehicles built before September 1, 1988 will conform to Secure Lighting Requirements upon determination of need and discretionary judgment by the appropriate modifying Government agent.
