`TERMINOLOGY - MOTOR VEHICLE LIGHTING
`
`The following are definitions of common terms used in SAE Standards
`SCOPE:
`and Recommended Practices pertaining to motor vehicle lighting.
`
`A Seasoned bulb operated at design mean spherical
`ACCURATE RATED BULB:
`Candlepower and having its filament(s) positioned within +0.25 mm, and with
`its pins oriented within +5 deg, of nominal design positions. Rated bulbs
`Shall be seasoned at rated voltage for 1% of their design life or 10 h
`max imum,
`
`indivisible assembly which.contains a source of light and which is
`An
`BULB:
`normally used in a lamp.
`
`such as a housing or lens.
`
`The geometric centroid of a plane area which is
`CENTROID OF A LENS AREA:
`perpendicular to the axis of reference of the vehicle and upon which the
`projection of the functional
`lighted lens area falls. As an example:
`The
`axis of reference for lamps mounted on the front and rear of a vehicle is the
`longitudinal axis of the vehicle.
`DEVICE: Any piece of equipment or mechanism designed to serve a special
`purpose or perform a special function.
`LAMP:
`A divisible assembly which contains a bulb or other light source and
`Sometimes an optical system such as a lens and/or a reflector, and which
`provides a lighting function.
`.
`
`LIGHT: Visible radiant energy.
`MULTIPLE COMPARTMENT LAMP:
`A device which gives its indication by two or
`more separately lighted areas which are joined by one or more conmon parts,
`
`SAETechnical Board Rules providethat: “This reportis published bySAEto advancethestate oftechnical and engineering sciences.
`Theuseof this report is entirely voluntary, and its applicability and suitability for any particular use,including any patentinfringement
`arising therefrom,is the sole responsibility of the user."
`mo,
`SAE reviews each technicalreport atleast every five years at whichtime it may be reaffirmed, revised, or cancelled. SAE invites your
`written comments and suggestions.

`A Tamp shall be deemed to be "optically combined" if
`OPTICALLY COMBINED:
`both of the following conditions exist:
`It has two or more separate light sources, or a single light source that
`operates in different ways (for example, a two ‘Filament bulb).
`Its optically functional
`lens area is wholly or partially common to two or
`more lamp functions.

`
`An array of two or more separate lamps on each

`side of the vehicle which operate together to give a signal.
`
`An indivisible assembly which provides a mechanical, electrical, or

`lighting function, for example, sealed beam unit or flasher.

`

`RATIONALE:
`
`J387 NOV87
`
`In FMVSS 108, paragraph S4.4.1, it is stated that "...no clearance lamp may be
`combined optically with any tail lamp or identification lamp..." Similar wording
`occurs in subsection 14 of CMVSS 108.
`
`lamps are being manufactured and installed on
`For lack of this definition,
`trailers that combine the clearance lamp functions under one lens, with two
`closely-spaced bulbs. This clearly violates the spirit and intent of these
`safety standards.
`
`This definition harmonizes well with ECE Requlation 48, page 2, paragraph 2.6.5,
`
`"Reciprocally Incorporated Lamps."
`
`RELATIONSHIP OF SAE STANDARD TO ISO STANDARD:

`
`APPLICATION:

`The following are definitions of common terms used in SAE Standards and
`Recommended Practices pertaining to motor vehicle lighting.
