Applicability
Introduction
Some vehicles may experience a condition where the inner Daytime Running Light/Turn Signal lens becomes distorted and bubbled in appearance. In addition the inner lens may appear cracked or separated.
NOTE
This condition should not be confused with normal yellow-orange color that occurs over time as the inner lens ages. Additionally this TSB does NOT address conditions with the outer headlamp lens.
Updated headlight assemblies have been developed to address this condition. The updated headlight assemblies have cosmetic changes so it is recommended to replace both the left and right assemblies together.
