Cadillac Escalade EXT HID headlight condensation and ballast failure issues requiring housing or ballast replacement on Cadillac Escalade EXT

Some Cadillac Escalade EXT owners report experiencing issues with HID headlights, including condensation buildup that can lead to low beam lamp failure and ballast damage. This condensation often occurs due to air or moisture leaks into the headlight housing. Additionally, some owners have reported ballast failure, particularly when liquid water enters the ballast, which can cause quick malfunction. In cases of a burnt-out HID headlight, it may be necessary to replace either the bulb or the ballast, with options like the PERDE Replacement Ballast available for 2007-2014 models. While resealing headlights can address condensation, many owners find that replacing the headlight assembly is a more effective long-term solution. Furthermore, signs of a failing ballast, such as inconsistent lighting or flickering, should prompt immediate attention to prevent further issues. Regular maintenance and timely replacement of faulty components are essential for ensuring the proper functioning and safety of the headlights.
