Nissan TITAN XD front headlight ballast damage from water intake requiring complete light fixture replacement on Nissan TITAN XD

Some Nissan TITAN XD owners report experiencing issues with front headlight ballast damage due to water intake, which often necessitates a complete light fixture replacement. This damage can occur because the ballast is located at the bottom of the headlight assembly and is secured with screws, potentially compromising the gasket and allowing water to enter. If the ballast and other components are affected, replacing the entire headlight assembly, including the control module ballast, may be required. Additionally, owners note that not all problems with Xenon HID headlight bulbs, such as buzzing, dimming, or flickering, are solely linked to a faulty ballast. When replacing the headlight assembly, some owners find it necessary to adjust the front end of the vehicle to access the screws, highlighting the complexity of the repair. Prompt resolution of these issues is crucial for maintaining the proper functioning of the vehicle's lighting system.
