Good To Know

Q: Why do xenon ballasts fail? A: Water entering the headlight housing is the leading cause of ballast failure, as it pools at the bottom where the module is mounted.

Q: Can I install this kit without removing the bumper? A: On many vehicles, accessing the bottom of the headlight housing to replace the ballast requires removing the front bumper and headlight assembly.
