Or do as I already posted that I'm planning - install the HID's, but retain the stock plugs & stash a halogen bulb so that if somehow the system fails I can still throw in a bulb & have lights. I'm not 'worried' about it & if anything, I think there's less chance of the HIDs failing than the halogen burning out - but I won't be able to buy a HID bulb on the road & like to plan ahead for contingencies.
And for me it's not about 'looking pretty' nearly so much as it's about improving the light output (without an irregular pattern).
