Hi! Looking for feedback and/or insight on an issue I am having with lowbeam headlights on 03 TL. When I turn on lights I never know if both low-beam are going to come on. Sometimes both operate fine, sometimes only the driver side comes on, sometimes only the passenger side, and sometimes neither side. All other lights are fully operable. I am told it could be the igniters of these high-voltage lamps. Any feedback would be a great help in troubleshooting the issue. Thanks!
