2.4.6.1 Conducted emissions. Electromagnetic emissions shall not appear on DC leads and
interconnecting control leads in excess of the limits in figures 2 and 3 for narrowband and
broadband emissions, respectively.
2.4.6.2 Radiated emissions. Narrowband electric field emissions shall not be radiated in excess
of the limits in figure 4 when measured at a distance of one meter. Broadband electric field from
all equipment and subsystems, including radiated switching transients from (1) automatic cycling
of electronic or electrical switching circuitry, or (2) manual switching shall not be radiated in
excess of the limits in figure 5 when measured at a distance of one meter. Above 30 MHz the
limits for both narrowband and broadband electric field radiated emissions shall be met for both
horizontally and vertically polarized waves.
2.4.7 Weather resistance. Warning lights shall be exposed to 56 cycles of the solar radiation
level in figure 6 (where one 24 hour duration of figure 6 is one cycle). No deviation of spectral
distribution for thermal effects shall be allowed. Warning lights shall be mounted as in the
vehicle with actual attaching hardware. Subsequently, warning lights shall meet the
requirements of 2.2.3 and 2.3.2.
2.4.8 Heat aging. Warning lights shall show no evidence of cracking, warping, or crazing after
exposure to ambient temperatures of not less than 200 °F for not less than 240 hours.
Subsequently, warning lights shall meet the requirements of 2.1.1 and 2.3.2.
2.4.9 Dust. Warning lights shall meet the requirements of SAE J575 paragraph 4.3 for dust
exposure. Subsequently, warning lights shall meet the operation requirements of 2.3.1, except
the test duration shall be five minutes.
2.5 Identification and markings. Unless otherwise specified (see 6.2), identification and
marking shall be permanent and legible, and shall include as a minimum, the manufacturer s
CAGE code number, the warning light voltage rating, and CID PIN (see 6.3).
2.6 Installation instructions. Each warning light shall be furnished with complete instructions
covering the installation of the warning light. A wiring diagram showing all of the electrical
connections to be made shall be included in the installation instructions.
2.7 Workmanship. The workmanship shall be such quality as to assure that warning lights
furnished under this CID are free of defects that compromise, limit, or reduce performance or
intended use. Warning lights shall be free of burrs, corrosion, scratches, sharp edges, loose
components, chips, and unnecessary oil or foreign materials.
3. Regulatory requirements.
3.1 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or
environmentally preferable materials should be used to the maximum extent possible provided
that the material meets or exceeds the operational and maintenance requirements, and promotes
economically advantageous life cycle costs. The offeror/contractor is encouraged to use
