Reliability Testing
Philips Lumileds conducts extensive reliability stress testing before the introduction of new products to ensure that they meet the reliability
expectations of the automotive market. The development of SignalSure includes reliability test simulations for both high voltage (24V) jump start and
high voltage (18V) alternator failure conditions to ensure LED survivability, performance and quality integrity as well as design margin allowance.
