It's important to note that a new ballast may not necessarily fix the headlight issue. You may need to replace other components like the igniter, wiring, plugs, and/or bulbs. A faulty igniter can also damage the replacement ballast. Avoid using grease or gel on any connections, and ensure a good condition foam gasket is used between the ballast and housing to prevent water from entering.

If water is entering the headlight, address the leaks before installing the replacement ballast. This is a direct plug-and-play replacement that does not require any programming or coding of the vehicle. The ballast can be installed on either the left or right headlight.

To diagnose the issue properly, try moving the working ballast to the non-working side. If the headlight then starts working, the replacement ballast will fix the problem. If the issue persists, there might be a different underlying problem that needs to be addressed.
