I don't have a view on whether to use HID high beam or not, but I have an HID low beam and almost never use my high beam. With the stock lights I rode with high and low day and night, and got very few indications it was a distraction to other drivers, though it did get noticed. The HID is brighter, has longer range, and the left hand dark spot is easier to live with, though I would like to fill this some way, some day.
The ballast I mounted on the plastic horizontal 'shelf' to the left of the headlight nacelle, and is completely 'sealed' as far as I can see though it may not do duty in outer space! It is one of those temporary mounts that may outlive me using cable ties (what else). The shelf is a little flexible which is a little concerning, but this may help dampen any shock to the unit. If I make it permanent, which may just mean new cable ties, I think I will mount it on a piece of soft foam.
Regarding duty cycle of the bulbs, it would seem to me that these would far outlast a regular bulb as there is no physical filament to vibrate. I think the listed life is 30,000 hours, a lot of riding to be sure.
There is no effect - that I can see - on GPS use.
As already mnetioned there is a lot on this topic in the archives, worth looking at. Let us know how it works.
