Consumer Description

3 year old truck. The left headlight enclosure gained water and caused the whole headlight system to have issues. Water caused the Headlights to Flash high beams (both), turn off and blinkers not to work. This defect the whole side that is effective. This can cause other drivers or the owner to have an accident. 6 months later, Now the right side headlight is doing the same. I’m out of warranty with only 40k miles. The seal is not strong enough to keep water out the enclosure. This can also cause the whole light system to shut down while driving. Very dangerous especially at night.
