3.8.2.5 TESTS, WARNING LIGHT SYSTEM.
The lighting manufacturers shall furnish and certify or the ambulance manufacturer shall measure
and record the total average current load of the standard emergency warning light system on the
vehicle as manufactured at the regulated voltage of 14.2 V, when operated in the mode which
draws maximum current. This load current test shall be conducted during the "ambulance's
electrical system test" (3.7.6 and AMD Std. 005). The warning light system and related
components and devices shall conform to temperature conditions in 3.4.2 and be tested and
approved by an Automotive Manufacturers Equipment Compliance Agency (AMECA)
accredited laboratory independent from the lighting device manufacturer's own labs and listed
with the AMECA for compliance with the requirements in this specification.
3.8.3
FLOOD AND LOADING LIGHT (EXTERIOR).
Flood and loading lights shall be not less than 191 cm (75 in.) above the ground and
unobstructed by open doors. Floodlights shall be located on the sides, and a patient loading
light on the rear of the ambulance. They shall be firmly fastened to reinforced body surfaces,
below the roofline. When specified by the purchaser (see 6.2-w) two flood lights shall be
furnished on each side, and two patient loading lights shall be furnished on the rear. These flood
lights shall be mounted on fixed body surfaces, and should have the maximum possible spacing
between them. The lamp(s) H-V shall be projected downward, either mechanically or optically,
at an angle of 12 to 18 degrees from the horizontal plane and the lighting on each side of the
ambulance shall provide a minimum of 800 beam candle power and produce a flood light pattern
similar to a H7619 sealed beam lamp. Floodlight switches shall be located on the cab console
and control each side independently. Loading light(s) shall provide a minimum of 500 candle
power beam and shall illuminate the area surrounding the back loading doors. The light(s) shall
produce a light pattern equivalent to a 4406 sealed beam. Loading light(s) shall automatically be
activated when rear doors are opened and may be incorporated with the FMVSS backup
lighting system.
3.8.4
SPOTLIGHT.
A hand held spotlight shall be provided with a minimum 100,000 CP lamp, corrosion-
proof housing with momentary switch, and minimum 244 cm (8 ft.) heavy-duty coiled
cord. It shall be hard wired to the vehicle 12 volt DC system (for anti-theft reasons) and
stowed in a holder in a compartment/area, accessible to the driver and passenger. When
specified (see 3.15.3-25), a remote controlled spotlight shall be furnished, having an "ON"/
"OFF" panel switch and variable speed fingertip control. Searchlight shall be a minimum
13 cm (5 in.) diameter, 100,000 CP sealed beam. Lights shall be operable over 360 degrees
horizontal sweep and approximately 90 degrees vertical range. Remote control, exterior,
light housings shall be chrome plated, bronze, brass, or other materials with intrinsically corrosion
resistant construction.
3.8.5
AMBULANCE INTERIOR LIGHTING.
The basic interior ambulance lighting configuration shall be designed to minimize electrical
loads and include: A driver's compartment dome light; instrument panel lights; master
switch panel; and console light(s). When specified (see 3.15.3-33), a map light for the
front seat passenger shall be furnished. Lighting shall be designed and located so that no
glare is reflected into the driver's eyes or his line of vision, from switch control panels or other
