PRODUCT DESCRIPTION
Lamps serve as important components of the whole vehicle. However, the reliability test standards of lamps and their accessories are numerous and complicated, and the test standards vary from one main engine factory to another, thus causing poor universality of such standards.
Test Cycle
2-3 months, during which comprehensive certification plan, testing and other services will be provided
Product Scope
LED lamp beads, photodiodes, phototransistors, laser assemblies
