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.

MIL-STD-1179E

4.3 Lamp and equipment combinations.

4.3.1 Lamp, reflector, or associated equipment combination. Two or more lamps, reflective devices or items of associated equipment may be combined if the requirements for each lamp, reflective device, and item of associated equipment are met. No high-mounted stop lamp shall be combined with any other lamp or reflective device.

4.3.1.1 Turn signal lamp combinations. No turn signal lamp may be combined optically with any lamp (other than a stop lamp) that produces more than 1/5 the light intensity of the turn signal lamp at test points of H-V, H-5L, H-5R, and 5U-V, nor more than 1/3 of the intensity of any test point on or above the horizontal. (See SAE J575 for definition of test points.)

4.3.1.2 Turn signal and stoplamp combinations. No turn signal lamp may be combined optically with a stop lamp unless the stop lamp is extinguished when the turn signal is flashed.

4.3.2 Headlamp combination, candlepower. When a parking lamp is optically combined with a turn signal, and the parking lamp is connected to be operated with the headlamps, the turn signal shall not be less than three times the candlepower of the parking lamp at any test point on or above horizontal, except that at H-V, H-5L, H-5R, and 5U-V, the turn signal shall not be less than five times the candlepower of the parking lamp. (See SAE J575 for definition of test points.)

4.4 Service lamp wiring requirements.

4.4.1 Stoplamp actuation. Stoplamps shall be actuated upon application of service brakes provided the vehicular light switch is in stop light, service drive or park position. For wheeled vehicles 1/, stoplamps shall override or be independent of the hazard warning signal.

4.4.2 Hazard warning signal actuation. The vehicular hazard warning signal operating unit shall operate independently of the ignition or equivalent switch, and when energized shall cause all turn signal lamps to flash simultaneously, provided the vehicular light switch is in stop light, service drive, or park position. Stoplamps for wheeled vehicles 1/ shall override the hazard warning signal or, as an option, stoplamps shall be on an independent circuit.

4.4.3 Head, parking and clearance lamp actuation. On all vehicles, parking lamps, clearance lamps, side-marker lamps and taillamps shall be energized when the headlamps are energized. The taillamps, identification lamps (if applicable) and side-marker lamps shall be energized when either the parking or clearance lamps are energized.

1/ Applicable only to new production wheeled vehicles manufactured after September 1, 1998.

Retrofit, rebuild, or other modifications for military vehicles built before September 1, 1998 will conform to this requirement upon determination of need and discretionary judgement by appropriate modifying Government agent.
