HID headlights won't come on

If they are "factory", a scan with a PST II/PIWIS will show what is wrong; if they are "post deleivery", the diagnostics will be manual..............

They're factory. What's a PST II/PIWIS?

It's a Porsche computer that they hook up to your car that can diagnose where the problem is.

I am having an issue with mine right now.. When I turn the switch on, most of the time they come on. Sometimes, they wont or will both flicker like they want to fire up but dont. I just last night kept tapping on the switch and this made them flicker more. I think it is a faulty switch. When the lights are on, they work perfectly which makes me think it has nothing to do with the lamps or ballasts...

Also, the switch is most likely the least expensive part to replace.

Good luck!
