CLEARANCE, SIDE MARKER, AND
IDENTIFICATION LAMPS— SAE J592e
SAE Standard
Report of Lighting Division approved January 1037 and last revised by Lighting Committee July 1072.
J. Scope— This standard provides test methods and requirements for
clearance, side marker, and identification lamps.
2. Definitions
2.1 Clearance Lamps— Lamps which show to the front or rear of a
vehicle, mounted on the permanent structure of the vehicle as near as
practicable to the upper left and right extreme edges to indicate the
overall width and height of the vehicle.
2.2 Side Marker Lamps— Lamps which show to the side of the
vehicle, mounted on the permanent structure of the vehicle as near as
practicable to the front and rear edges to indicate the overall length of
the vehicle. Additional lamps may also be mounted at intermediate
locations on the sides of the vehicle.
2.3 Combination Clearance and Side Marker Lamps— Single lamps
which simultaneously fulfill the requirements of clearance and side
marker lamps.
2.4 Identification Lamps— Lamps used in groups of three, in a hori-
zontal row, which show to the front or rear or both, having lamp
centers spaced not less than 6 in (15,2 mm) nor more than 12 in (30.4
mm) apart, mounted on the permanent structure as near as practicable
to the vertical centerline and the top of the vehicle to identify certain
types of vehicle.
$. Laboratory Requirements
3.1 General Requirements— The following sections from SAE J575
are a part of this standard:
3.1.1 Section B— Samples for Test
3.1.2 Section C— Lamp Bulbs
3.1.3 Section D— Laboratory Facilities
3.1.4 Section E— Vibration Test
3.1.5 Section F— Moisture Test
3.1.6 Section G-Dust Test
3.1.7 Section H— Corrosion Test
3.1.8 Section J— Photometric Test
3.1.9 Section L— Warpage Test on Devices with Plastic Lenses

CLEARANCE, SIDE MARKER, AND IDENTIFICATION LAMPS
3.2 Color Test— The color of light from front clearance lamps,
front and intermediate side marker lamps, and front identification
lamps shall be yellow (amber). The color of light from rear clearance
lamps, rear side marker lamps, and rear identification lamps shall be
red. (See SAE J578.)
3.3 Plastic Materials— Any plastic materials used in optical parts
shall comply with the requirements set forth in SAE J576.
3.4 Photometric Requirements— Photometric tests shall be made at
a distance of at least 4 ft (1.2 m). The H-V axis of a clearance or identi-
fication lamp shall be taken as parallel with the longitudinal axis of the
vehicle. The H-V axis of a side marker lamp shall be taken as normal
.to the longitudinal axis of the vehicle. The H-V axis of a combination
clearance and side marker lamp shall be taken as parallel with the
longitudinal axis of the vehicle when checking clearance lamp test
points, and normal to this vehicle axis when checking side marker test
points. In all cases, the H-V axis shall be taken as parallel to the sur-
face on which the vehicle stands.
Candela requirements for clearance, identification, and side marker
lamps are shown in Table 1. Combination clearance and side marker
lamps shall comply with both clearance and side marker minimum
candela requirements.
APPENDIX
As a matter of information, attention is called to the typical sockets
shown in SAE J567.

a The maximum light output for red clearance and identification lamps is 15 cd. When red
clearance lamps are optically combined with stop or turn signal lamps, this maximum applies on
or above the horizontal.
bThe requirements for side markers used on vehicles less than 80 in (2m) wide may be met for
inboard test points at a distance of 15 ft (4.5m) from the vehicle on a vertical plane that is per-
pendicular to the longitudinal axis of the vehicle and located midway between the front and
rear side marker lamps.
