Specification for Testing Automotive LED Modules.
Product Code: USCAR33
Date Published: 2013-02-19
This specification is a general level subsystem light source specification that establishes test
requirements of Light Emitting Diode (LED) components and modules for use in automotive lighting
The completed test data to this test specification is intended to be provided to the OEM by the Tier I
lamp set maker as part of the lamp assembly PPAP. Re-testing shall be required if any portion of the
approved LED modules experiences a design, manufacturing or component change.
This document shall be applied to systems that meet the requirements for design, performance and
validation established by government standards.
The LED module is defined as the LED devices and any electronics required to properly energize the
LEDs using vehicle electrical power system along with any associated electrical wiring, connectors
and thermal management system. Samples shall be tested as a subsystem and considered one test
sample for the entire test sequence. A failure of any component in the test sample shall constitute a
failure of the entire sample. If other manufactures components are intended to be approved for use
in the LED modules, then those possible combinations of components shall be considered a new LED
module and shall also be tested.
Additional testing may be required by individual OEM’s to meet specific EMC, quality, reliability and
The following tests are to be performed under the following conditions:
• New sample
• Design or process change made to an existing module
• Completion of one calendar year as noted in the “ANNUAL TESTS” Table shown in the
Appendix. (Note: Production process control data, collected at a shorter interval per an
approved control plan, may be substituted if approved by customer’s responsible engineer and
