Here's the thing with the AUTO and HID thing that I read a while back when I was researching this exact thing.
With AUTO, the truck will turn them on before the vehicle starts. When you crank the vehicle, the voltage will drop and, according to what was in the article, can damage the components during the drop. Then, they go back to full power after the start cycle.
It's believed that the HID arc should be at full power to "warm up" for a specified amount of time before being turned off and stuff... What happens if you start it up and then pull outside and it's bright? Then they go right off again, wasting a start up cycle.
That's basically the cliff notes of what it said.
I use my lights manually because I don't use the auto because I can remember to turn lights on when shit gets dark and I like to run with just the parking lights for a while at dusk to look good.
Solid & concise explanation, I trust the source, so that's all I need to hear. That's how I'll operate my lights too... I'm all about the parking-lights-at-dusk thing also... hell that was the whole point in asking Ducati to hook me up with the Evil Eye setup anyway.
