1. Your headlight housing is refllector type, not projector. You will caused glare to oncoming traffic if you put HID (kit or oem) in such housing. While the roads look brighter to you, it will blind the oncoming traffic. And I am not talking about improper adjustment of the light height or anything. Shine your light to a wall, HID pattern should look like this: ____/--------/------ . The pattern will be messed up if you put them inside nonprojector-type headlight. In addition, Armada seats really tall from the ground, so the glaring effect may be amplfied even more~
2. How long is the warranty of that HID kit of yours? 2 yrs? 3 yrs? 1 yr? Make sure you know how to claim the warranty and also able to find replacement parts for that specific HID kit brand of yours. Non philips/oscram hid kit (bulbs and ballast) especially the Taiwan or Korean's kit typically last not long; a yr or less is common.

However, you are still OK since your reflector headlight housings are clear lenses, not textured. The light pattern may be incorrect, but will not be totally wrong. The most important thing is that you are happy, right? .
