I'm having an issue with my stock HID headlights flickering randomly. This has been happening for over a year and has gotten increasingly worse, to the point where they have just turned off while driving down the freeway. When they turn off, if I switch between daytime lights and headlights, they come back on. I have search through the threads on this site and can't seem to find a definitive solution. I have already replaced both bulbs.
