MIL-DTL-14465 Lights, Composite, 24 Volts Direct Current \(Nominal\) VehicularThis specification covers two types of vehicular composite light assemblies each consisting of a service driving light, infrared driving light, blackout driving light, and a blackout marker light. The vehicular composite light assemblies are referred to herein as "light assemblies". The light assemblies are designed for use on military tracked vehicles equipped with nominal 24-volt \(V\) direct current \(dc\) electrical systems \(see 6.1\).

from 6 to 30.5 m from the light with the top of the light beam directed not less than 10 below the

horizontal. The beam distribution on a level road at a point 30.5 m from the vehicle blackout

driving light shall be 9 m wide. Beam candlepower values at various positions shall be as

specified in table IV (see 4.2.4.4).

3.5 Interface requirements. Each light assembly shall accommodate the following

requirements:

3.5.1 Interchangeability. To provide for interchangeability, light assemblies fabricated

in accordance with this specification shall have external dimensions that conform to the

applicable drawing or military standard. Electrical connectors and mounting dimensions and

location, shall also conform to the requirements of the applicable drawings or military standard

(see 4.2.5.1).

3.6 Support and ownership requirements.

3.6.1 Identification marking. Unless otherwise specified (see 6.2), the light assembly

shall be permanently marked in accordance with MIL-STD-130 or equivalent, and shall

prominently display at least the manufacturer s name or trademark, manufacturer s part number,

cage code, and military part or identification number (PIN) on the interior of the light assembly.

Spare parts of the assembly which will be serviced and stocked for Army Field Service shall

have a PIN permanently marked thereon. A tag shall be affixed to the light assembly for storage

or handling identification (4.2.6.1).

3.6.2 Safety. The light assembly shall pose no hazards, physically or electrically to

personnel (4.2.6.2).

3.6.3 Finish. Unless otherwise specified (see 6.2), cleaning, treating, plating, and

painting of parts of the light assembly shall be in accordance with the MIL-DTL-53072. All

exposed parts requiring paint topcoat shall be topcoated with a forest green paint conforming to

MIL-DTL-64159 Type II (see 4.2.6.3).
