While driving with brights on, the lights would randomly shut off, and to turn them back on I would have to shut off my headlights and turn them back on low beams. This is a very dangerous problem and I hope you can help me.
Anytime you have a safety concern I recommend contacting your local dealership Service Department to inquire about any existing Recalls or Notices. These vehicles have been known to have the multi-function switch fail.
Light working and then not sounds like a loose wire or break in a wire inside the wiring harness. If has recently been worked on, look in those areas for loose connections, etc.
