I don't believe one=the other but I was rear ended the other day.
Conicentally, I've been getting the Check Highbeam fault the following day onwards.

My High Beams work. I have Quad Xenons - one being the Bi-Xenon.

I'm not a 12V Guru. Is it just the load resistor that is possibly shot and I just need to replace that. That, of which I can manage, cause I know where it's screwed into each side of the car, and I suppose I can manage replacing, splicing and soldering...just match it up to how it's currently setup, but replace the current *golden* load resistor with a new one.
