(ii) Provision must be made for rigid or shock-absorbing mounting.
(iii) The axis of the light beam must be parallel to the roadway and the longitudinal axis of the vehicle.
(iv) The lamp must be mounted on the centerline of the rear exterior of the vehicle or with the optical center of the lamp not more than fifteen inches from the centerline.
(v) The deceleration warning light system must be mounted as nearly as practicable at the same height as the existing stop lamps on the vehicle.
(vi) Visibility of the deceleration lamps to the rear must not be obstructed by any part of the vehicle or load thereon.
(b) Meet Type I or Type II requirements and test methods for a deceleration alert system.
(i) Type I - the system must:

(C) Have a center-to-center (optical axis) distance between two adjacent compartments ((should not exceed)) not exceeding six inches.
(D) Have three compartments. The center compartment emits a green light and is energized when the vehicle operator has the accelerator depressed. The two outer compartments emit an amber light and are energized when the operator releases the accelerator and prior to applying pressure to the foot brake pedal. When the amber lights are energized, the green light is deenergized. When pressure is applied to the foot brake pedal, the amber lights are deenergized and the vehicle's stop lamps operate in the normal manner. SAE Standard J578d is adopted for color chromaticity boundaries.
(E) Meet the requirements under the following sections of SAE J575g: Section B, samples for test; Section C, lamp bulbs; Section D, laboratory facilities; Section E, vibration test; Section F, moisture test; Section G, dust test; Section H, corrosion test; and Section J, photometry. If plastic material is used in optical parts it must comply with the requirements set forth in SAE J576c.
(F) Measure the beam candle power with the H-V axis taken as paralleled to the longitudinal axis of the vehicle. The candle power measurements for the center green compartment must be made with the incandescent filament of the lamp at least ten feet from the photometric screen.
Beam candle power measurements of the two amber compartments ((shall)) must be made by either of the following methods:
(I) The two compartments may be photometered together provided that a line from the optical axis (filament centers) of each compartment to the center of the photometer sensing device does not make an angle of more than 0.6° with the photometer (H-V) axis.
(II) Each compartment may be photometered separately by aligning its axis with the photometer and adding the value at each test point.
Table 1 lists the design candle power requirements for the two outer amber lights, and Table 2 lists the design candle power requirements for the center green light.

(a) Be mounted on the front and rear of the bus, above the windows, as high and as widely spaced laterally as practicable but in no case ((shall)) will the lateral spacing of these lamps be less than forty inches.
(b) Be mounted so that the vision of front, signals to the front and rear signals to the rear ((are not unobstructed)), is not obstructed by any part of the vehicle from 5° above to 10° below the horizontal and from 30° to the right to 30° to the left of the centerline of the bus.
(c) Have the switch which activates the signal lamps be actuated by movement of the stop signal to the extended position.

The "on" period of the flasher must be long enough to permit the bulb filament to come up to a full brightness.
(g) Signal lamps must be aimed two inches below level at twenty-five feet and straight ahead. An aiming tolerance of from three inches up to seven inches down and ten inches right or left will be allowed.
(h) Only be actuated by the driver of a private carrier bus whenever such vehicle is stopped on the highway for the purpose of receiving or discharging passengers, except:
(i) When the passengers boarding or alighting do not have to cross a highway and the bus is stopped completely off the main traveled portion of the roadway; or
(ii) When the bus is stopped at an intersection or place where traffic is controlled by a traffic officer or official control signal.
((EXCEPTION:
Buses that do not stop upon the roadway to load or discharge passengers are exempt from the requirements of this section.))
(2) Rear turn signal lamp and stop lamp lenses must be amber in color to avoid confusion with signal lamps and the message on the warning sign.
