LAMP BULBS AND SEALED UNITS—SAE J573d

SAE Standard

Report of Lighting Division approved March 1918 and last revised by Lighting Committee December 1968.

Scope— Many of the lighting devices on motor vehicles are legally required and are essential to safe operation on the highway. To maintain performance, it is important that the bulb and sealed unit types employed be readily available, when needed. throughout the country in normal service channels. Therefore, this SAE Standard lists an assortment of current popular types, together with their characteristics. which are recommended for use wherever practicable. It is recognized that because of constantly changing and improving technology, the list may be incomplete. Also, instances may arise in the design of some devices which require the employment of other types while achieving the desired performance.

cWhen bulb No. 81 is operated at 5.5 V, it supplies approximately 3 cp. Therefore, if may be used instead of the 3 cp No. 63 in commercial vehicle applications wherein relatively high voltage drop is experienced at the end of long lines.
dOver 2000 hr at 14 V.
e Filament spacing is denoted by dimension x (0.110Χ0.020 in.) in Fig. 1.
f Plane of pins with respect to filament is 90±15 deg. On remaining types filament orientation is random.

a Letter designations are defined as follows; F-Fog; H-Sealed Beam Headlamp; S-Spot; X-Heavy Duty Service.
b For convenience and simplification of life testing, all lamps designed for use on 6V circuits are life tested at 7V, and all lamps designed for use on 12V circuits are life tested at 14V. In general the life at average service voltages is longer.
c See SAE J571.
