My motorcycle headlight turns on whenever the key is on, regardless of whether the engine is running. There's a momentary cut when the starter button is depressed but other than that, they're always on. This kind of power cycling is hard in HID lights.

I haven't actually done this yet. It's just an idea that I plan to execute on my CBR600F4i when my HID projectors arrive next week. If anyone out there knows anything about electronics please don't hesitate to leave feedback. Thanks.

By the way, "IGN (+)" is power supplied only when the key is in the "ON" position

 

That's pretty much how mine is on my f2. Except I only have one relay. Works good.
